Speech Recognition in Python
Science & Technology
Introduction
In this article, we will dive into the world of speech recognition in Python. We will explore the process of setting up speech recognition using Python libraries and creating a basic script for speech recognition. Let's get started!
To use speech recognition in Python, the two main libraries we need to install are SpeechRecognition and Pyttsx3. We can install these libraries using pip by running the following commands:
pip install SpeechRecognition
pip install pyttsx3
Building the Speech Recognition Script
To begin with, we import the necessary libraries in our Python script, including SpeechRecognition and Pyttsx3. We create a recognizer object that will help us understand the speech input. Then, we set up an infinite loop to continuously recognize speech input from the microphone.
Within the loop, we adjust for ambient noise, listen to the microphone input, and extract the text using Google as the recognition source. We handle errors such as unknown value errors and restart the process when needed. Finally, the recognized text is printed to the console.
Testing the Speech Recognition Script
To test the speech recognition script, save it to a Python file (e.g., main.py) and run it from the command line by navigating to the script's location and executing python main.py. The script will recognize spoken words and display the text output accordingly.
