Microsoft just beat OpenAI, Google, and ElevenLabs on speech-to-text simultaneously — on price, speed, and accuracy. [MAI-Transcribe-2](https://microsoft.ai/news/mai-transcribe-2-is-the-fastest-most-accurate-and-cheapest-speech-recognition-model-in-the-world/), which dropped September 3rd, is priced at $0.10 per audio hour. That’s 72% cheaper than the API rate Microsoft charged for its own previous model, and less than a third of what OpenAI’s hosted Whisper costs. If you’re routing production transcription through any of the major providers right now, this is worth a look before your next billing cycle.

## The Numbers That Matter

MAI-Transcribe-2 claims first place on [the FLEURS benchmark](https://huggingface.co/datasets/google/fleurs) across 60 languages with a 5.2% average word error rate. On speed, Microsoft says the model processes at roughly 410x real-time — one hour of audio in about 10 seconds. That’s 10x faster than GPT-Transcribe, 7x faster than ElevenLabs ScribeV2, and 5x faster than Gemini 3.5 Transcribe.

The pricing comparison is where things get stark:

| Provider | Price/hr | Speed vs MAI-T2 | 
|---|---|---|
| MAI-Transcribe-2 | $0.10 | — | 
| OpenAI GPT-Transcribe | $0.36 | 10x slower | 
| ElevenLabs ScribeV2 | ~$3.67* | 7x slower | 
| Gemini 3.5 Transcribe | N/A public | 5x slower | 
| Groq Whisper v3 Turbo | $0.04 | Faster, no diarization | 

For teams running call center workloads, the math is blunt: 100,000 hours annually drops from $36,000 to $10,000.

## The Developer Feature Set

Raw price and benchmark numbers are only half the story. MAI-Transcribe-2 ships with four features that cover the most common production transcription needs.

**Speaker diarization** segments a recording by speaker and returns labeled segments with timing metadata. Enable it with `diarization.enabled: true`. **Word-level timestamps** give you offset and duration for every word — useful for video editors, search indexing, and transcript navigation. **Keyword biasing** via `phraseList.phrases` boosts recognition accuracy for domain-specific terms, product names, and abbreviations that trip up generic models. And the **transcription style toggle** — `"clean"` vs `"verbatim"` — handles whether you want readable output (fillers removed) or a full compliance record (every “um” and false start preserved).

Code-switching between Hinglish, Spanglish, and other common blended pairs is handled automatically with no extra configuration.

## Quick Integration

You need an Azure subscription and [a Microsoft Foundry resource for Speech](https://learn.microsoft.com/en-us/azure/ai-services/speech-service/mai-transcribe). Once that’s in place, you’re one API call away:

```
curl --location 'https://YourResourceName.cognitiveservices.azure.com/speechtotext/transcriptions:transcribe?api-version=2025-10-15' --header 'Content-Type: multipart/form-data' --header 'Ocp-Apim-Subscription-Key: <YourSpeechResourceKey>' --form 'audio=@"YourAudioFile.wav"' --form 'definition={ 
  "enhancedMode": {
    "enabled": true,
    "model": "MAI-Transcribe-2"
  }
}'
```

Accepted formats: WAV, MP3, FLAC. File size cap: 300 MB. Also available through the MAI Playground for no-code testing, and via OpenRouter if you’re already routing model calls through there.

## Read the Fine Print

Here’s what Microsoft’s own documentation says: MAI-Transcribe-2 is in public preview, “without a service-level agreement and not recommended for production workloads.” That’s a meaningful caveat. If you’re building anything customer-facing that can’t tolerate occasional downtime or behavior changes, you’re taking on risk right now.

The $0.10 rate is explicitly a promotional price through end of 2026. Microsoft hasn’t published what permanent pricing looks like. Building a 2027 business case around the launch price is a gamble. The rapid deprecation cycle adds to that risk: MAI-Transcribe-1 launched in April and was already deprecated by August — five months. Plan your migration windows accordingly.

One more thing: this is Azure-only infrastructure. Unlike Deepgram or AssemblyAI, which run cloud-agnostic, you’re committing to an Azure subscription and a Foundry resource. If you’re already in Azure, there’s no added friction. If you’re not, that’s the real cost to evaluate — not the $0.10 rate.

## The Bigger Picture

MAI-Transcribe-2 isn’t an isolated product launch. It’s part of Microsoft’s push to build its own AI models — speech, image, voice — instead of reselling OpenAI capabilities. The [VentureBeat coverage](https://venturebeat.com/infrastructure/microsoft-ais-mai-transcribe-2-undercuts-openai-google-and-elevenlabs-on-price-and-speed) frames this as Microsoft pursuing “AI self-sufficiency.” The pacing is aggressive and intentional.

For the speech API market, this is the second major price cut in six months from a Tier-1 vendor. If the promotional rate sticks or becomes the new normal, it forces Deepgram, AssemblyAI, and ElevenLabs to respond. That’s good for developers regardless of which provider you end up with.

## Bottom Line

If you’re using a hosted transcription API for call center, clinical, or media workloads — or paying OpenAI’s $0.36/hr Whisper rate — MAI-Transcribe-2 is worth piloting. Test on your own audio before committing; FLEURS and real-world accents don’t always agree. Watch the fine print on promotional pricing before locking in a cost model. And keep an eye on the deprecation timeline. Full details in the [official documentation](https://learn.microsoft.com/en-us/azure/ai-services/speech-service/mai-transcribe).
