AudioProcessor

AudioProcessor is a Python library that provides a simple interface to perform various audio processing tasks such as recording, voice-to-text conversion, text-to-voice conversion, and audio playback.

Installation

To use AudioProcessor, make sure you have the following packages installed:

• pyaudio
• pydub
• pydub.effects
• speech_recognition
• webrtcvad
• gtts

You can install these packages using pip:

pip install pyaudio pydub speechrecognition webrtcvad gtts

Usage

To use AudioProcessor, simply import the AudioProcessor class and create an instance:

from audio_processor import AudioProcessor processor = AudioProcessor()

Recording audio

To record audio, use the record_audio method:

processor.record_audio("output_file.wav")

This method records audio from the microphone and saves it to a .wav file.

Voice-to-text conversion

To convert an audio file to text, use the audio_to_text method:

text = processor.audio_to_text("input_file.wav")

Text-to-voice conversion

To convert text to an audio file, use the text_to_audio method:

processor.text_to_audio("Hello world!", "output_file.wav")

Audio playback

To play an audio file, use the play_audio_file method:

processor.play_audio_file("input_file.wav")

Class Parameters

The AudioProcessor class can be initialized with the following parameters:

• frame_duration_ms: (int) Frame duration in milliseconds for Voice Activity Detection (default: 30)
• sample_rate: (int) Sample rate of the audio in Hz (default: 16000)
• chunk_size: (int) Chunk size for audio playback (default: 1024)
• vad_mode: (int) Voice Activity Detection mode, an integer between 0 and 3 (default: 2)
• log_level: (int) Logging level, an integer between 0 and 50 (default: logging.WARNING)
