I’m trying to create a bot that checks if users send audio responses and acts accordingly. Currently, my bot only processes text messages and disregards audio ones. Here’s the handler I’ve implemented:
async def handle_user_response(update: Update, context: ContextTypes.DEFAULT_TYPE) -> int:
connection = sqlite3.connect(database='db.db')
cursor = connection.cursor()
I need to add a check to see if the incoming message is text or audio (assuming audio won’t have accompanying text). However, right now, the bot only acknowledges text messages and ignores audio responses. This is what I have for handling the message:
if update.message.text:
query = f"UPDATE users SET problem = '{update.message.text}' WHERE id = {context.user_data['user_id']}"
else:
audio_msg = update.message.audio
audio_file = await context.bot.get_file(audio_msg.file_id)
audio_filename = f'audio/{audio_msg.file_unique_id}.ogg'
await audio_file.download(audio_filename)
query = f"INSERT INTO audio (id, audio_name) VALUES ({context.user_data['user_id']}, '{audio_filename}')"
cursor.execute(query)
connection.commit()
query = f"UPDATE users SET problem = 'in audio message' WHERE id = {context.user_data['user_id']}"
And this is how I defined the handler in my ConversationHandler:
SELF_PROBLEM: [MessageHandler(filters.TEXT | filters.AUDIO, handle_user_response)],
I haven’t been able to find a specific handler for audio messages, so I opted to use filters.AUDIO instead.
Another thing to try is using both filters.VOICE | filters.AUDIO since voice notes are separately categorized. Voice notes are sometimes mistaken for regular audio messages. Be sure to handle both cases in your code, as this might be causing the issue if you’re using voice notes. 
From my experience, handling audio messages with python-telegram-bot can be quite straightforward once you get the hang of it. One thing you might want to check is whether update.message.audio is indeed capturing your audio messages. A quick way to verify is by logging some details when an audio message is received, like this:
if update.message.audio:
print(f'Received audio: {update.message.audio.file_id}')
Make sure your bot has permission to download files; sometimes, the issue might stem from incorrect permissions. Also, ensure the audio is actually being sent as an audio file and not a voice note, which would be accessible via update.message.voice. If it’s a voice message, use filters.VOICE instead of filters.AUDIO. Debugging these aspects might help you handle the audio messages more effectively.
To effectively manage audio messages using python-telegram-bot, try utilizing the update.message.document attribute when the audio file might be sent as a document type instead. In some cases, audio files may inadvertently be categorized as documents. Ensure your filters in the handler also consider this type by incorporating filters.DOCUMENT. Additionally, examine whether the bot can access the source folder and permissions are appropriately set. Double-check the file path specification when downloading audio files to prevent any unexpected file handling issues.
