From Phone Call to Formatted Email in 80 Lines of Python — AI Voice Memo Cleanup with Telnyx

AI Voice Memo to Email — an 80-line Flask webhook that answers a phone call, gathers a spoken memo, runs it through AI Inference to clean up grammar and extract structure, and delivers a formatted email. One API key for voice, AI, and messaging. No third-party services.

The Voice Memo Problem

Voice memos are the fastest way to capture a thought — you speak, you're done. But what you get is a rambling audio blob that nobody (including you) wants to read later. The raw transcript is worse: no punctuation, false starts, filler words, and no structure. You still have to manually clean it up before it's useful as an email, a status update, or a meeting summary.

The existing solutions split the problem across multiple services. A transcription service converts audio to text. An LLM API cleans up the text. An email service sends the result. Three vendors, three API keys, three bills, three points of failure.

The AI Voice Memo to Email example does all of it on one network — Telnyx Call Control handles the phone call, Telnyx AI Inference cleans up the transcript, and Telnyx Messaging delivers the email. One API key. One Flask file. About 80 lines of Python.
