# Speech-to-Text

Speech-to-Text is a Google Cloud service that converts spoken language into written text using machine learning models. It supports real-time and batch audio transcription, multiple languages, and domain-specific tuning. The service can process audio from various sources such as files or streaming input, making it useful for voice commands, call analytics, and caption generation.

Supported languages for each model are listed in the [Table of Supported Models](https://cloud.google.com/speech-to-text/v2/docs/speech-to-text-supported-languages). If additional languages are provided, recognition result will contain recognition in the most likely language detected. The recognition result will include the language tag of the language detected in the audio. When you create or update a Recognizer, these values are stored in normalized BCP-47 form. For example, "en-us" is stored as "en-US". |
