Real-time speech recognition in Python refers to the ability of a computer program to transcribe spoken words into written text in real time. You can use a library like SpeechRecognition to recognize speech in real-time in Python. It supports several various engines and APIs, such as Microsoft Bing Voice Recognition and Google Speech Recognition. 


Real-time voice recognition in Python has a wide range of uses, including: 

  • Voice-controlled assistants: These virtual assistants, like Siri or Alexa, can be operated via voice commands. 
  • Speech-to-text transcription: This tool turns audible words into written text and is useful in professions including journalism, law, and medicine. 
  • Voice biometrics: This application uses a person's distinctive voice patterns to authenticate and identify them. 
  • Real-time language translation: This program helps people who speak various languages communicate more easily by translating spoken words from one language to another. 
  • Speech-based accessibility: Applications that assist people with disabilities, such as text-to-speech or speech-to-text for the visually impaired. 


Here is how you can recognize speech in real time in Python:

Code

In this solution we're using SpeechRecognition and PyAudio libraries.

Dependent Libraries : 
import speech_recognition as sr

r = sr.Recognizer()
with sr.Microphone() as source:
    r.adjust_for_ambient_noise(source)
    print("Say something!")
    audio = r.listen(source)

try:
    text = r.recognize_google(audio)
    print("You said: {}".format(text))
except:
    print("Sorry")

Instructions

Follow the steps carefully to get the output easily.

  1. Install SpeechRecognition and PyAudio on your IDE(Any of your favorite IDE).
  2. Open terminal and install the above mentioned libraries using the command given in 3 & 4 steps.
  3. Speech Recognition - pip install SpeechRecognition.
  4. PyAudio - pip install PyAudio.
  5. Copy the snippet using the 'copy' and paste it in your IDE.
  6. Run the file to generate the output.


I hope you found this useful. I have added the link to dependent libraries, version information in the following sections.


I found this code snippet by searching for 'Speech recognition using python' in kandi. You can try any such use case!

Environment Tested

I tested this solution in the following versions. Be mindful of changes when working with other versions.

  1. The solution is created in PyCharm 2021.3.
  2. The solution is tested on Python 3.9.7.
  3. SpeechRecognition version-3.9.0.
  4. PyAudio version-0.2.13.


Using this solution, we are able to implement speech recognition using python with simple steps. This process also facilities an easy way to use, hassle-free method to create a hands-on working version of code which would help us to implement speech recognition using python.
