Learn how to transcribe an audio file using Speech-to-Text API.
Soniox Speech-to-Text API supports high-accuracy transcription in 50+ of the world's most spoken languages, with language auto-detection included. Let's dive in and transcribe an audio file.
Get API key
Create a free Soniox Account and login into Soniox Console to create an API key.
Note: API keys are bound to projects. Click on "API keys" under "My First Project" section to create one.
Configure environment
Store the API key in the SONIOX_API_KEY environment variable to prevent accidental exposure.
Note: Alternative is to put the API key in .env file, if you already have it configured.

- Create a transcription session.
