About

Inworld Realtime STT is a realtime streaming STT API that understands users beyond their words. It combines low-latency speech recognition with voice profiling, extracting emotion, vocal style, accent, age, and pitch directly from raw audio so downstream LLMs and TTS systems can respond with more adaptive, expressive behavior. Developers can stream audio in real time, transcribe complete files, or extract voice profile signals through one unified API, with realtime bidirectional streaming over WebSocket, synchronous transcription for full audio files, voice profile signals on every streaming chunk, and multi-provider support through a single model ID. Every audio chunk can produce a realtime profile of the speaker with confidence scores, giving LLMs structured context such as whether a user sounds sad, frustrated, soft, high-pitched, or calm.

About

MAI-Transcribe-2-Streaming is a low-latency streaming transcription model built for real-time speech applications, delivering transcripts in 60 languages with automatic, continuous language detection. Rather than waiting for someone to finish speaking, it produces initial partial transcripts just over 100 ms after receiving audio, revises them as more context arrives, and commits stable text quickly. This allows voice applications to begin reasoning, calling tools, or displaying live transcripts while a person is still speaking. Microsoft reports that the model ranks No. 1 for both final and partial transcript accuracy on Artificial Analysis. MAI-Voice-2.1 complements it with multilingual text-to-speech across 23 languages and 26 locales, allowing a single voice to switch languages while maintaining the same speaker identity and adopting native accents.
