Translating audio with Lara (audio-to-audio)

Lara supports audio-to-audio translation through a dedicated API, allowing you to translate spoken content directly from one language to another and receive the result as an audio file.

This feature is designed for programmatic and voice-based use cases where both the input and the output are audio.

What is audio-to-audio translation

With audio-to-audio translation:

  • the input is an audio file

  • the output is a translated audio file

  • speech is translated end-to-end without manual intermediate steps

You do not need to separately manage speech-to-text or text-to-speech processes.

 

Access and availability

Audio-to-audio translation is available through:

  • Lara’s API

  • Lara’s SDKs

This feature is intended for developer and integration use cases and is not available in the Lara web interface.

 

Supported languages

Audio-to-audio translation supports a wide range of languages and locale variants.

Because language availability depends on the underlying speech capabilities and may evolve over time, the most up-to-date list of supported languages is maintained in the developer documentation.

For the current list of supported languages and locale codes, refer to:
https://developers.laratranslate.com/docs/translate-audio 

 

Usage and pricing

Audio-to-audio translation usage is calculated based on audio duration.

Usage is billed per minute of processed audio.

Current rates:

€ 0.08/ $ 0.08 per minute

Examples:

1 minute of audio → €0.08 / $0.08
60 minutes of audio → €4.80 / $4.80

 

Typical use cases

Audio-to-audio translation is commonly used for:

  • voice-based applications and assistants

  • audio content localization

  • speech-driven workflows

  • multimedia and accessibility scenarios

Developer documentation

Detailed technical information — including supported audio formats, request parameters, limits, SDK usage examples, and supported languages — is available in Lara’s developer documentation.
