# Speech-to-Text Transcription for Voice Calls

### 19, Apr 2021

Voice API users can now transcribe speech to text in real time, with a beta version of our speech-to-text transcription tools.

Real-time speech-to-text transcription is available in six languages:

* German - `"de"`
* English - `"en"`
* Spanish - `"es"`
* French = `"fr"`
* Italian = `"it"`
* Polish - `"pl"`

Transcription can be turned on and off on-demand at any point during a call by sending a [transcription\_start](https://developers.telnyx.com/api/call-control/dial-call) or [transcription\_stop](https://developers.telnyx.com/api/call-control/dial-call) command along with the call's `call_control_id`. Transcription will automatically end if a call ends (through being hung-up by the end-user, or through an API command).

Transcription is billed in 15-second increments, at a cost of $0.05 / minute (or $0.0125 per 15 seconds - that's more than 30% cheaper than competing on-call transcription offerings from Twilio!).
