Recognizer Class in SpeechRecognition
Key Implementations done by SpeechRecognition using the Recognizer class.
Primary purpose of Recognizer instance is to recognize speech.
Each instance comes with a variety of settings and functionality for recognizing speech from an audio source.
Creating a Recognizer instance is easy. In your current interpreter session, just type:
>>> r = sr.Recognizer()
Methods for Recognizing Speech
Each Recognizer instance has seven methods for recognizing speech from an audio source using various APIs
Of the seven, only recognize_sphinx() works offline with the CMU Sphinx engine. The other six all require an internet connection.
Each recognize_*() method will throw a speech_recognition.RequestError exception if the API is unreachable.
For recognize_sphinx(), this could happen as the result of a missing, corrupt or incompatible Sphinx installation.
For the other six methods, RequestError may be thrown if quota limits are met, the server is unavailable, or there is no internet connection.
Adding Audio Files for Speech Recognition
Now, record the WAV File so that it can be translated to text. Any WAV file can be taken
Speech Extraction Google API
import speech_recognition as sr harvard=sr.AudioFile('myrecord.wav') r = sr.Recognizer() with harvard as source: audio=r.record(source) print (type(audio)) print (r.recognize_google(audio))
The text will be recognized from audio file "myaudio.wav" and will be printed
