Fixing Audio Recording Issues with Speech Recognition Package on Linux Mint

Introduction

In this article, we will discuss how to fix common audio recording issues when using the Speech Recognition package (Google Speech-Recognition) in Linux Mint for online meetings or calls to get transcripts. We will cover the basics of the Speech Recognition package, its installation, and some troubleshooting steps.

Prerequisites

Before we begin, ensure that your system meets the following requirements:

• Linux Mint 19 or higher
• Python 3.x installed
• Internet connection for downloading Google Speech Recognition API

Installing Google Speech Recognition Package

To install the Google Speech Recognition package, follow these steps:

1. Open a terminal window and update the package list:

sudo apt update

2. Install the required dependencies:

sudo apt install python3-pip python3-dev python3-setuptools python3-wheel

3. Install Google Speech Recognition:

pip3 install SpeechRec

Recording Audio and Getting Transcripts

To record audio and get transcripts using the Speech Recognition package, follow these steps:

1. Open a new Python file in your preferred text editor:

nano record_audio.py

2. Add the following code:

 import speech_recognition as sr
 r = sr.Recognizer()
 with sr.Microphone() as source:
 print("Listening...")
 audio = r.listen(source)
 try:
 print("Recognizing...")
 query = r.recognize_google(audio, language='en-in')
 print(f"User said: {query}
")
 except Exception as e:
 print("Say that again please...")
 print("Error occurred: " + str(e))
 

3. Save and close the file.
4. Run the script:

python3 record_audio.py

5. Speak into the microphone when you see the "Listening..." message.

Audio Recording Issues and Troubleshooting

If you encounter any audio recording issues, follow these troubleshooting steps:

1. Check the microphone settings:

amixer

Make sure that the microphone is not muted and the volume is up.

2. Check the PulseAudio configuration:

pulseaudio --config

Edit the configuration file and add the following lines:

load-module module-udev-detect

load-module module-null-sink sink_name=Virtual1 sink_properties.device.description="Virtual Output"

load-module module-loopback source=Virtual1 sink=auto

Save and close the file.

3. Restart PulseAudio:

pulseaudio --start

4. Check the Google Cloud Speech API key:

Make sure that you have a valid Google Cloud Speech API key. You can get a free key from the Google Cloud Speech API Quickstart page.
