Can I code this? An AI Text-to-Speech Narration Tool

Sending text to an existing text-to-speech API and returning an audio file is mostly a thin, honest wrapper — you're integrating an existing voice model, not building one.

Why CanICodeThis says Build it

  • Submitting text and calling an existing text-to-speech API to generate an audio file is a bounded, well-documented integration
  • Choosing from preset voices via the API is standard form work
  • Storing and organizing generated audio files is ordinary CRUD

The parts that'll cause problems

  • The actual voice-synthesis model is genuinely hard, specialist ML research — you're integrating an existing one, and API costs scale with usage
  • Cloning a specific real person's voice raises real consent and safety considerations beyond preset voices
  • Fine control over pacing, emphasis, and emotional tone depends entirely on the underlying API's capability

MVP scope

  • A text input box
  • Voice selection from an existing text-to-speech API's presets
  • Generate and download the audio file

Postpone to v2

  • Custom voice cloning (real consent/safety review needed first)
  • Fine-grained pacing and emphasis controls
  • Batch narration of long documents

The build prompt

Build me a text-to-speech tool: a text box, voice selection from an existing text-to-speech API's presets, and a button that generates and returns a downloadable audio file. Use an established third-party API for the actual voice synthesis — don't attempt to train your own model.
