Definition
Text-to-speech (TTS) converts written text into spoken audio using a synthesized voice. In a product video, TTS can provide narration without a live voice recording. The output still needs editorial review for pronunciation, pacing, language quality, accessibility, and any voice or usage rights that apply.
Scenario in a product workflow
A team can generate two short samples of a product name before recording a long tutorial. Compare pronunciation and pacing, then review the chosen voice's permitted use. If an acronym sounds wrong, rewrite or provide a pronunciation guide where supported rather than hoping the full narration will fix itself.
How to apply it
Treat synthesized speech as a production choice, not an approval step. Confirm pronunciation, language, pacing and voice usage rights with a human reviewer.
A practical review
Create a short sample before generating a long script. Review product names, numbers, abbreviations and language pronunciation with a fluent speaker where possible. Confirm voice permissions and provider terms for commercial use.
A decision to make before production
Test names, abbreviations, numerals and mixed-language phrases in short samples first. Keep the chosen voice and pronunciation notes with the script so a later regeneration remains consistent.
How it differs from recorded narration
Text-to-speech synthesizes audio from text. Recorded narration captures a person's performance. Both need review for pronunciation, pacing, clarity and rights; neither is automatically correct.
When a team uses the term “text to speech” in a brief or review, agree on the intended meaning before production. That prevents the script, visual plan and success measure from drifting apart.
