Using the Google Cloud Speech API

The Google Speech API uses a powerful machine learning model to convert audio to text. The API recognizes over 110 languages and can process them as a stream or from stored audio files. The Speech API can perform the conversion by three methods—synchronous recognition, asynchronous recognition, and stream recognition.

We'll perform a simple recipe to use the Speech API to convert a recorded message to text using the synchronous recognition method.

Getting ready

The following are the initial setup verification steps for the creation of the network before the recipe can be executed:

1. Create or select a GCP project
2. Enable billing and enable the default APIs (some APIs like BigQuery, storage, monitoring, and few a others are enabled automatically)
3. Enable the Google Cloud Speech API for the project
4. Make sure that the code has access to GCP APIs using the Application Default Credential strategy or direct API keys
