google-cloud-speech

Google Cloud Speech API (docs) enables developers to convert audio to text by applying powerful neural network models.

Quick Start

$ gem install google-cloud-speech

Authentication

This library uses Service Account credentials to connect to Google Cloud services. When running on Compute Engine the credentials will be discovered automatically. When running on other environments the Service Account credentials can be specified by providing the path to the JSON file, or the JSON itself, in environment variables.

Instructions and configuration options are covered in the Authentication Guide.

Example

require "google/cloud/speech"

speech = Google::Cloud::Speech.new

audio = speech.audio "path/to/audio.raw",
                     encoding: :raw, sample_rate: 16000
results = audio.recognize

result = results.first
result.transcript #=> "how old is the Brooklyn Bridge"
result.confidence #=> 0.9826789498329163
