The Cloud Speech API enables developers to convert audio to text by applying powerful neural network models. The API recognizes over 80 languages and variants, to support your global user base.
Quick StartIn order to use this library, you first need to go through the following steps:
Install this library in a virtualenv using pip. virtualenv is a tool to create isolated Python environments. The basic problem it addresses is one of dependencies and versions, and indirectly permissions.
With virtualenv, it’s possible to install this library without needing system install permissions, and without clashing with the installed system dependencies.
Supported Python VersionsPython >= 3.5
Deprecated Python VersionsPython == 2.7. Python 2.7 support will be removed on January 1, 2020.
Mac/Linuxpip install virtualenv
virtualenv <your-env>
source <your-env>/bin/activate
<your-env>/bin/pip install google-cloud-speech
Windows
pip install virtualenv
virtualenv <your-env>
<your-env>\Scripts\activate
<your-env>\Scripts\pip.exe install google-cloud-speech
Example Usage
from google.cloud import speech_v1
from google.cloud.speech_v1 import enums
client = speech_v1.SpeechClient()
encoding = enums.RecognitionConfig.AudioEncoding.FLAC
sample_rate_hertz = 44100
language_code = 'en-US'
config = {'encoding': encoding, 'sample_rate_hertz': sample_rate_hertz, 'language_code': language_code}
uri = 'gs://bucket_name/file_name.flac'
audio = {'uri': uri}
response = client.recognize(config, audio)
