Meet MAI Transcribe 1, the most accurate transcription model in the world across 25 languages.
Speech is the most natural way humans communicate, often in noisy environments – conference rooms, phone lines, busy streets – across many languages. Today we’re introducing MAI Transcribe 1, a robust and efficient multilingual speech-to-text model that gives developers building global products a single model that scales well across languages, accents, and production environments. MAI Transcribe 1 is now available on Microsoft Foundry.
MAI Transcribe 1 achieves the lowest Word Error Rate against competitive speech-to-text models. On FLEURS (25 languages), it outperforms Scribe v2, Whisper-large-V3, GPT-Transcribe, and Gemini 3.1 Flash-Lite.
The model maintains competitively high accuracy across all 25 supported languages, making it adaptable for global products and resilient to a wide range of accents or speaking styles.
Our model delivers incredible batch transcription speeds 2.5x faster than our current Microsoft Azure Fast offering. We know that speed and efficiency are essential for all production workloads. We’ve worked incredibly hard to ensure that we deliver this lightning fast performance whilst maintaining SOTA performance across 25 languages.
Benchmarks are only part of the story. When it comes to production use cases such as voice agents, meeting transcription, and call center analytics, audio is rarely clean. MAI Transcribe 1 was built with challenging recording conditions in mind, reliably handling background noise, low-quality audio recordings, and overlapping speech.
Cafe scenario
TRANSCRIPTION:
Hey, so I was hoping to change my flight, if that’s at all possible. It’s currently set for 10 p.m. tonight, but I’m really trying to switch to something earlier, ideally sometime before 6 p.m. Is that something we could maybe look into?
Office Scenario (in Spanish)
TRANSCRIPTION:
Bueno, ya estamos listos, ¿no? Eh, ¿podemos please checar que esté prendido my transcribe one? SÃ, está. Super. Entonces, vamos a empezar. Oh, oh, someone else is joining us. Oh, hello. Please come in. Join us. We’ll switch to English, no problem. SÃ, sÃ, sÃ. Bienvenido. Bienvenido.
Concert scenario
TRANSCRIPTION:
Okay, listen. I have this absolutely unhinged idea, and I need you to roll with me. Help me make an agent that will literally buy tickets for my favorite band the second they are available.
We are passing efficiency gains directly to customers: MAI Transcribe 1 is priced at $0.36 per hour of audio, setting the standard for quality, speed, and price for production ASR.
MAI Transcribe 1 is in phased rollouts with Copilot’s Voice mode and Microsoft Teams to provide accurate conversation transcripts, that can be used for various downstream tasks.
MAI Transcribe 1 is now in public preview on Microsoft Foundry.
You can also experience MAI Transcribe 1 in the newly launched Microsoft AI Playground.
MAI Transcribe 1 delivers latency low enough for a wide range of use cases while providing very high accuracy.
MAI Transcribe 1 supports a wide range of applications, from media and content tasks such as subtitle generation, podcast transcription, and video accessibility, to enterprise needs such as meeting archives, compliance recording, and legal discovery. It can also power analytics workflows, including call center QA, customer insight extraction, and searchable audio libraries, as well as large scale data pipelines for processing audio archives used in ML training, search indexing, and summarization.
Low latency also makes MAI Transcribe 1 a good choice for real-time tasks. Be it meeting transcription, video close captioning, or dictation.
If you’re building a voice agent, MAI Transcribe 1 is the foundational layer. Accurate transcription is what allows underlying LLMs to interpret intent effectively. It directly shapes user satisfaction and task completion rates.
By combining MAI Transcribe 1 (speech-to-text) with MAI Voice 1 (text-to-speech) and your chosen LLM you can build a robust solution to power voice experiences.
