OpenAI has announced GPT Transcribe, a speech-to-text model that converts completed audio files and live audio streams into text. The model supports keyword hints and multiple language hints to improve accuracy for specialized terminology and multilingual speech, addressing transcription needs in technical and domain-specific fields.

OpenAI announced GPT Transcribe, a speech-to-text model that processes completed audio files, streamed file transcripts, and committed turns in Realtime sessions over WebSocket. The model supports unstructured context, keyword hints, and multiple language hints to improve transcription of domain terms, multilingual audio, and code-switching.
Why it matters
The model's ability to handle keyword hints and language hints means it can be tuned for specialized vocabularies and multilingual contexts—a capability that could reduce transcription errors in fields like medicine, law, and software development where precise terminology matters. Support for Realtime sessions over WebSocket suggests real-time transcription use cases alongside batch processing.
What to watch
The announcement does not include pricing, availability date, API access details, or region restrictions. No information is provided about how GPT Transcribe compares to existing transcription services or whether a second model (GPT-live-transcribe) mentioned in the title will be detailed separately.
OpenAI announced GPT Transcribe, a speech-to-text model designed to handle multiple transcription scenarios. The model accepts three types of input: completed audio files, streamed file transcripts, and committed turns in Realtime sessions transmitted over WebSocket. This flexibility allows users to integrate the model into both batch processing pipelines and real-time communication systems. To improve accuracy on specialized content, GPT Transcribe supports unstructured context, keyword hints, and multiple language hints. These features are intended to enhance transcription of domain-specific terms, multilingual audio where speakers switch between languages, and code-switching scenarios where speakers mix languages within a single conversation. The model's architecture suggests OpenAI is positioning it as a tool for technical teams, international organizations, and industry-specific applications where standard speech-to-text often stumbles on jargon or language mixing. However, the announcement does not disclose pricing, launch timeline, API availability, or competitive positioning relative to existing transcription services.
OpenAI's introduction of GPT Transcribe reflects a strategic effort to expand its AI offerings beyond text generation into audio processing. The model's design—supporting both batch and real-time transcription paths—suggests an attempt to serve both asynchronous workflows (transcribing recorded files) and synchronous use cases (live transcription during calls or meetings). The emphasis on keyword hints and language hints indicates OpenAI is aware that generic speech-to-text often fails on technical vocabulary and mixed-language content; these features are particularly relevant to developers, medical professionals, and international teams who regularly encounter code-switching or specialized terminology.
