With sr.AudioFile(path_to_audio_file) as source: The below code is then responsible for loading the audio file from the designated path, and then converting the speech into text using Google Speech Recognition: # open the file The first step is to initialize your recognizer like so: # initialize the recognizer Interpreting Speech from a Fileīefore starting, make sure you placed an audio file containing english language, in the current working directory for maximised simplicity, or somewhere you know the path (such as ‘./audio_files/my_audio_file.wav’). In this tutorial, we will be using Google Speech Recognition, because it is rather simple to use, efficient, and does not require any API key. It is now very handy, you have access to several speech recognition engines, that have different use cases: Then, in a new Python file, you can import it the following way: import speech_recognition as sr

Therefore, we don’t need to build any machine learning model from scratch, this library provides us with wrappers for several well known public speech recognition APIs (such as Google Cloud Speech API, IBM Speech To Text, etc.).Īs usual, we will start downloading the module: pip install SpeechRecognition pydub Instead, we will be using the SpeechRecognition library. We will obviously not be constructing from A to Z such a library, that would be way beyond this tutorial.

This field can be very complex and top Python libraries result from decades of hard work from experts. Speech recognition is the ability to detect and identify words and phrases in spoken language and subsequently convert them into human, readable text.
