Automate Telegram Voice Note Sharing with Python 3

Looking to automate voice message delivery, audio recordings, or spoken notifications from your Python applications? This guide walks you through sending voice note files (OPUS format) to Telegram users using Python 3 and the WhatsMate Telegram Gateway REST API. Perfect for Python developers, data scientists, and automation enthusiasts who want to integrate voice messaging into their Python-based workflows.

📋 Prerequisites

Before you begin, ensure you have:

  1. A WhatsMate Telegram Gateway account - Required for API access
  2. Recipient registration - Each recipient must register with the Gateway first
  3. Python 3 installed - Version 3.6+ recommended for modern Python features
  4. Basic Python knowledge - Familiarity with Python programming
  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: Recipients must register with the WhatsMate Telegram Gateway before they can receive messages. Unregistered users 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 to a Telegram user 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 gateway instance ID, Client ID, and Secret
  • Line 14: Replace 12025550108 with the target phone number (including the country code)
  • Line 15: Replace ../assets/martin-luther-king.opus with the path to your OPUS voice note file
  • Line 16: Replace anyname.opus with the desired filename for the voice note
  • Line 17: 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

4. Send Your Voice Note

Run the Python script to deliver your voice note to Telegram:

python3 send-telegram-opus-individual.py

🔧 Common Use Cases

This automation approach is ideal for:

  • AI/TTS integration - Generate voice messages using text-to-speech (TTS) APIs and deliver them to Telegram for automated announcements, notifications, or interactive voice responses
  • Machine learning integration - Deliver voice outputs from speech recognition or audio generation models
  • Data science workflows - Send voice notifications or results from data analysis pipelines
  • Audio notifications - Deliver spoken alerts or voice notifications from Python systems
  • Voice message automation - Send pre-recorded voice messages or announcements via Telegram from Python applications
