Send Voice Note Files to Telegram Groups in Python 3 - Complete Guide

🚀 Automate Telegram Group Voice Note Sharing with Python 3

Looking to deliver voice notes, audio recordings, or spoken messages to Telegram groups directly from your Python applications? This comprehensive guide walks you through sending voice note files (OPUS format) to Telegram groups using Python 3 and the WhatsMate Telegram Gateway REST API. Perfect for Python developers building automation scripts, data pipelines, web applications, or machine learning systems that need reliable group voice messaging capabilities.

📋 Prerequisites

Before you begin, ensure you have:

1. A WhatsMate Telegram Gateway account - Required for API access (sign up for a 2-week trial)
2. Group registration - The Telegram group must be registered with the Gateway first
3. Python 3 installed - Version 3.6+ recommended for modern Python features
4. Basic Python knowledge - Familiarity with Python programming and package management
5. Voice note file ready - Have the OPUS file you want to send available locally
6. Requests library - Install via pip install requests if not already available

⚠️ Important: Telegram groups must be registered with the WhatsMate Telegram Gateway before they can receive messages. Unregistered groups will not receive any messages from the Gateway. Registration instructions are available on the official WhatsMate site.

📝 Step-by-Step Implementation

Follow these steps to send your first voice note file to a Telegram group from a Python application:

1. Copy the Python Code Template

Start by copying the following source code into your Python file:

2. Configure a few Parameters

Customize these key parameters in the Python code:

• Lines 8-10: Replace YOUR_GATEWAY_INSTANCE_ID_HERE, YOUR_OWN_ID_HERE, and YOUR_OWN_SECRET_HERE with your Telegram gateway credentials
• Line 14: Replace Muscle Men Club with your target Telegram group name
• Line 15: Replace 19159876123 with the phone number of the group admin (including country code)
• Line 16: Replace ../assets/martin-luther-king.opus with the path to your OPUS voice note file
• Line 17: Replace anyname.opus with the desired filename for the voice note
• Line 18: Replace I have a dream with an optional caption for your voice note

3. Install Required Dependencies

Ensure you have the required Python packages installed:

pip install requests

For virtual environment setup (recommended):

# Create and activate virtual environment
python3 -m venv venv
source venv/bin/activate  # On Windows: venv\Scripts\activate

# Install dependencies
pip install requests

4. Run Your Python Script

Execute the Python script to deliver your voice note to the Telegram group:

Basic execution:

python3 send-telegram-opus-group.py

With virtual environment:

source venv/bin/activate  # On Windows: venv\Scripts\activate
python send-telegram-opus-group.py

Make script executable (Linux/macOS):

chmod +x send-telegram-opus-group.py
./send-telegram-opus-group.py

🔧 Common Use Cases

This automation approach is ideal for Python developers building:

• AI/TTS integration - Generate voice messages using text-to-speech (TTS) APIs and deliver them to Telegram groups for automated announcements, notifications, or interactive voice responses
• Data science workflows - Send voice notifications or analysis results to team groups from Python data pipelines
• Machine learning systems - Deliver voice outputs from speech recognition, audio generation, or NLP models to relevant groups
• Web applications - Send voice announcements or updates to Telegram groups from Python web frameworks (Django, Flask, FastAPI)
• Automation scripts - Integrate voice messaging into Python automation scripts for system monitoring, alerts, or scheduled announcements
