# csm-conversation-bot
|
|
||||||
|
|
||||||
## Overview
|
|
||||||
The CSM Conversation Bot is an application that utilizes advanced audio processing and language model technologies to facilitate real-time voice conversations with an AI assistant. The bot processes audio streams, converts spoken input into text, generates responses using the Llama 3.2 model, and converts the text back into audio for seamless interaction.

## Installation
|
|
||||||
1. Clone the repository:
|
|
||||||
```
|
|
||||||
git clone https://github.com/yourusername/csm-conversation-bot.git
|
|
||||||
cd csm-conversation-bot
|
|
||||||
```
|
|
||||||
|
|
||||||
2. Install the required dependencies:
|
|
||||||
```
|
|
||||||
pip install -r requirements.txt
|
|
||||||
```
|
|
||||||
|
|
||||||
3. Configure the application settings in `config.py` as needed.
|
|
||||||
|
|
||||||
## Usage
|
|
||||||
1. Start the server:
|
|
||||||
```
|
|
||||||
python server.py
|
|
||||||
```
|
|
||||||
|
|
||||||
2. Open your web browser and navigate to `http://localhost:5000` to access the application.
|
|
||||||
|
|
||||||
3. Use the interface to start a conversation with the AI assistant.
