Microsoft AI on Thursday released MAI-Transcribe-2, a speech-recognition model the company says is faster, more accurate, and cheaper than anything OpenAI, Google, or ElevenLabs currently sells. Then it priced the thing at 10 cents per hour of audio.
That figure deserves a pause. When Microsoft AI shipped the first model in this line just five months ago, it charged $0.36 an hour. Thursday’s early-bird price cuts that by roughly 72%. For an enterprise processing 100,000 hours of call-center audio a year — a modest volume for a large bank or telecom — the bill drops from $36,000 to $10,000. At that level, transcription stops being a line item anyone argues about.
The release arrives as Microsoft executes a strategy that would have seemed implausible two years ago: building its own frontier-class models one modality at a time, then steadily swapping them into products that once ran on OpenAI’s technology. Transcription is the modality where that plan has moved fastest, and MAI-Transcribe-2 is its clearest proof point yet. It also offers a preview of how the world’s most valuable software company intends to compete in AI without depending on the partner it spent $13 billion to cultivate.
What MAI-Transcribe-2 does and why the feature list matters to enterprise buyers
The model transcribes audio in 60 languages, up from 43 in June’s MAI-Transcribe-1.5 and 25 in April’s original release. It runs on Microsoft Foundry, the company’s model marketplace for developers, and in MAI Playground, its testing environment. Microsoft says it built the model for the messy audio that real businesses generate — background noise, low-quality recordings, overlapping speech — rather than clean studio conditions.
More important than the language count is what Microsoft has bundled into the base product. Speaker diarization sorts out who said what in a multi-person recording, which is the difference between a wall of text and a usable meeting transcript. Word-level timestamps attach a precise time marker to every word, enabling search, editing, and alignment with video. Keyword biasing lets developers feed the model a list of drug names, product codes, or employee names so it stops mangling domain jargon. Automatic language identification means users no longer have to declare the language in advance.
Two features stand out for their specificity. A configurable output style offers a «verbatim» mode that preserves every «um,» false start, and stutter for compliance and legal teams, alongside a «clean» mode that strips fillers for readable captions and notes. And code switching handles conversations that drift between languages mid-sentence; Microsoft explicitly names Hinglish and Spanglish, a nod to the Indian and U.S. Hispanic markets where a single customer-service call might toggle languages a dozen times. Specialty vendors have historically charged premiums for each of these capabilities. Microsoft is including all of them for a dime.
How to read Microsoft’s FLEURS and Artificial Analysis benchmark claims
Microsoft makes three performance claims, each resting on a different measuring stick, and technical buyers should understand what each one captures and what it misses.
The first is that MAI-Transcribe-2 ranks number one on FLEURS across 60 languages with an average word error rate of 5.2%. FLEURS is a benchmark Google researchers published in 2022, built from native speakers reading roughly 2,000 sentences in each of 102 languages — about 12 hours of speech per language. It is the standard yardstick for multilingual speech recognition because it lets you compare a model’s Swahili against its Swedish on identical content. Word error rate, its metric, simply counts substitutions, insertions, and deletions against a human reference; 5.2% means roughly one word in 20 is wrong. But FLEURS is read speech, not conversation, and Microsoft’s average has actually risen from the 3.7% it reported for MAI-Transcribe-1.5 in June. That almost certainly reflects broader coverage rather than regression — averaging across 60 languages instead of 43 means folding in low-resource languages where every model struggles — but buyers should request the per-language breakdown.
The second claim is that the model ranks second on the Artificial Analysis word-error-rate leaderboard and defines that firm’s accuracy-latency Pareto frontier. Artificial Analysis is an independent benchmarker that tests models through their public APIs, measuring what a customer actually gets. Its index blends simulated agent conversations, European Parliament speeches, and corporate earnings calls, weighting heavily toward English business speech. In June, the firm ranked MAI-Transcribe-1.5 third at 2.4% WER, behind Alibaba’s Fun-Realtime-ASR-preview and ElevenLabs’ Scribe v2, while calling it the fastest model in the top 10. Climbing to second suggests Microsoft has cleared ElevenLabs. «Pareto frontier» is the phrase practitioners should note: it means no rival beats the model on accuracy without being slower, and none beats it on speed without being less accurate.
The third claim is raw speed — 10 times faster than OpenAI’s GPT-Transcribe, seven times faster than ElevenLabs’ Scribe v2, five times faster than Google’s Gemini 3.5 Transcribe, per Artificial Analysis evaluations. In batch transcription, speed matters less because anyone is waiting and more because throughput is cost. A model running at 300 times real-time needs a fraction of the GPU-hours of one running at 30 times. That efficiency is what lets Microsoft charge a dime and, presumably, still make money.
Three speech models in five months: inside Microsoft AI’s rapid release cadence
The pace is the story within the story. On April 2, MAI-Transcribe-1 launched with 25 languages at $0.36 per hour. On June 2, MAI-Transcribe-1.5 arrived with 43 languages, keyword biasing, and a third-place ranking on Artificial Analysis. Today, MAI-Transcribe-2 shipped with 60 languages, diarization, timestamps, code switching, a second-place ranking, and a price of $0.10.
Three releases in five months, each expanding language coverage by roughly 40% while adding features competitors gate behind premium tiers. That cadence is characteristic of a team that has settled on a stable architecture and is now turning the crank on data and scale — the phase where speech models tend to improve quickly and predictably. It is also the cadence of a company that intends to make transcription a commodity before anyone else can.
The organizational bet behind that speed is one Mustafa Suleyman, Microsoft AI’s chief executive, described to The Verge in April. He credited the first model to «a small, focused 10-person team» that had been «liberated from any of the bureaucracy,» with a larger surrounding group handling vendor management and data acquisition.
He also told The Verge the model ran at «half the GPU cost of the other state-of-the-art models,» calling it «a huge cost-saving» for Microsoft. Meta, Amazon, Google, and Anthropic have all experimented with similar flattened structures, The Verge noted. Microsoft’s transcription line is the most visible test yet of whether the approach produces commercial results rather than research papers.
Why Microsoft is building its own AI models despite its $13 billion OpenAI bet
Microsoft has invested more than $13 billion in OpenAI, and hosts OpenAI’s models across Azure, Office, and Copilot. For most of the past four years, the obvious question about any Microsoft-built model has been: why bother? The answer has sharpened over the past year, and it begins with independence.
When Microsoft hired Suleyman from Inflection AI in March 2024, along with most of Inflection’s staff, Salesforce CEO Marc Benioff read it as a declaration of intent. «Microsoft is building their own AI and I don’t think Microsoft will use OpenAI in the future. They’ll have their own frontier models,» Benioff told CNBC in January 2025. «That’s why they hired Mustafa Suleyman.» Benioff had his own motives — Salesforce competes with Microsoft and invests in Anthropic — but events have largely borne him out.
In October 2025, Microsoft and OpenAI restructured their partnership in a deal that, per Microsoft’s own announcement, allowed Microsoft to «independently pursue AGI alone or in partnership with third parties» for the first time. Suleyman told The Verge that renegotiation «unlocked [Microsoft’s] ability to pursue superintelligence,» and Microsoft announced its MAI Superintelligence team weeks later. In April 2026, the companies amended the deal again, ending Microsoft’s exclusive access to OpenAI’s models and eliminating Microsoft’s revenue-share payments, according to reports at the time. Each amendment loosened the tie. Each one was followed by more MAI models.
How Microsoft’s in-house models are cutting costs across Teams, Word, and Excel
The second half of the answer is margin. Every prompt Microsoft routes to an OpenAI model carries a cost. Every prompt it routes to its own model on its own GPUs carries a smaller one. In July, Bloomberg reported that Microsoft had begun using MAI models to answer a portion of user prompts in Word and Excel — products it had previously advertised as powered by OpenAI and Anthropic. TechCrunch framed the shift as part of a broader industry pullback on AI spending, with Amazon, Uber, Meta, and Accenture all reportedly trimming.
Transcription is the natural first target for this substitution because the problem is bounded and the metric is objective. Microsoft owns Teams, which generates an enormous volume of meeting audio. It owns Nuance, whose clinical documentation business runs on speech recognition. It owns the Azure speech services that thousands of enterprises already call. Every one of those workloads is a candidate to move onto MAI-Transcribe-2, and every hour that moves is an hour Microsoft no longer pays anyone else for.
Suleyman has been unusually candid that this is the point. Superintelligence, he told The Verge in April, «is really about, ‘Are these models capable of delivering product value for the millions of enterprises that depend on us to deliver world-class language models?'» Whatever one thinks of applying the word «superintelligence» to a transcription API, the commercial logic is plain: build the capability once, deploy it across a dozen products, and stop writing checks to a partner that is increasingly a competitor.
MAI-Transcribe-2 vs. OpenAI, Google, and ElevenLabs: the competitive picture
Microsoft’s release names four rivals: OpenAI’s GPT-Transcribe, Google’s Gemini 3.5 Transcribe, OpenAI’s older Whisper V3-Large, and ElevenLabs’ Scribe v2. It does not mention Deepgram, AssemblyAI, Speechmatics, or Rev — the specialists that have sold transcription to enterprises for a decade. Microsoft is positioning against the frontier labs, not the incumbents.
That framing is partly marketing and partly true. The frontier labs have treated speech as a checkbox feature of broader platforms, priced accordingly, and a dedicated model that beats them on speed by five to 10 times while matching their accuracy is a genuine differentiator. But the specialists will feel the price pressure most acutely. At $0.10 an hour, Microsoft is pricing at or below where many of them sell high-volume enterprise contracts, and it is bundling diarization, timestamps, and 60 languages into the base rate. The specialists’ remaining moat is domain depth — medical vocabularies, legal formatting, industry-specific integrations — and Microsoft’s keyword biasing feature is aimed squarely at it.
The one competitor Microsoft conspicuously does not claim to beat on accuracy is Alibaba, whose models have posted leading numbers on independent leaderboards for much of 2026. TechCrunch reported in July that some U.S. companies had begun evaluating Chinese models as cheaper alternatives despite security concerns. Microsoft’s pitch to those buyers is implicit but unmistakable: comparable accuracy, faster inference, lower price, and a vendor your compliance team already trusts.
The questions technical decision makers should ask before switching transcription vendors
For all its specificity on benchmarks, the release leaves several practical questions open. The first is duration: Microsoft calls $0.10 per hour a launch offer without naming an end date or a standard rate, and anyone building a cost model should get both in writing. The second is streaming. The release emphasizes batch throughput and long-form audio but says nothing about real-time transcription, which voice agents and live captioning require. Artificial Analysis maintains a separate streaming leaderboard, and Microsoft’s silence on it is notable.
The third is per-language accuracy. A 5.2% average across 60 languages could mean 3% on major languages and 12% on low-resource ones, so buyers with specific needs should test those languages directly. The fourth is diarization quality. Word error rate does not measure speaker attribution; a transcript can have near-perfect WER and still assign every other sentence to the wrong person. The release offers no diarization error rate or comparable metric.
The fifth is data handling. Enterprise transcription touches medical records, legal privilege, and financial disclosures, and the release says nothing about data residency, retention, or whether audio submitted to Foundry feeds future training. Microsoft’s April announcements described training data as a mix of human-curated recordings, contractor-recorded noisy audio, and «vast amounts of data from the open web,» per The Verge — a description that should prompt pointed questions from regulated industries. None of these gaps is unusual for a launch announcement, but they are exactly the questions that separate a leaderboard win from a production deployment.
What Microsoft’s speech model strategy reveals about its broader AI ambitions
Step back from the speech-recognition details and a pattern emerges that extends well beyond transcription. Microsoft’s AI unit now ships models for images, voice, transcription, code, reasoning, and cybersecurity. At Build in June, it announced seven new MAI models in a singlekeynote. Each follows the same playbook: target a well-defined modality, optimize aggressively for inference cost, price below the frontier labs, distribute through Foundry, and quietly swap the model into Microsoft’s own products.
This is not an attempt to build one model that beats GPT or Gemini at everything. It is an attempt to build a portfolio of specialized models that, in aggregate, let Microsoft serve most of its enterprise workloads without paying anyone else — and to sell the surplus capacity to everyone else at prices the specialists cannot match. Transcription happened to be the first modality where the approach fully matured, but the release notes for MAI-Transcribe-2 read less like a product announcement than a template.
Suleyman has spent two years talking about «humanist superintelligence» and AI assistants that are «accountable to them, on their side.» The vocabulary is lofty. The execution is a spreadsheet. Five months ago, Microsoft charged 36 cents to turn an hour of speech into text. On Thursday it charged a dime, threw in six features its rivals sell separately, and claimed the top spot on the industry’s standard multilingual benchmark. The company that spent $13 billion learning what frontier AI costs has decided it would rather own the factory than rent the output — and now it is selling the output for less than the rent.
MAI-Transcribe-2 is available now through Microsoft Foundry and MAI Playground.
