AI Gateway now supports streaming transcription
AI Gateway can now stream audio into transcription models and emit partial text, letting text-based agents accept lower-latency voice input without changing the agent itself.

Source Summary
AI Gateway now supports **streaming transcription** through the AI SDK’s **streamTranscribe** function. It accepts live audio and emits transcript deltas plus partial and final transcripts across compatible providers.
Practical Implication
Builders can add voice input by forwarding the live transcript to an existing text agent; swap the model string to change providers, and add speech generation only when spoken output is required.

The feature is **beta**, and the material gives no latency, accuracy, interruption-handling, or cost measurements. Full two-way conversation may be better served by a realtime voice system.
