The quick read
- Choose a licensed voice or obtain the required permission before creating a voice based on a real person.
- Test pronunciation, emphasis and pauses on the actual playback device.
Start with the listening task
A navigation instruction, an educational narration and a dramatic character require different pacing and expression. Write the script for listening: shorten tangled sentences, expand unfamiliar abbreviations and decide how numbers should be spoken. The voice model cannot repair an unclear message by tone alone.
Use identity responsibly
Choose a licensed voice or obtain the required permission before creating a voice based on a real person. Make the synthetic nature clear when listeners could otherwise misunderstand who is speaking. Review the provider’s current controls and terms for the intended use.
Listen in context
Test pronunciation, emphasis and pauses on the actual playback device. Check whether background music masks important words and provide a text alternative where useful. For an illustrative course lesson, listen to the complete paragraph rather than approving isolated sentences. A voice can sound natural while placing emphasis in the wrong place. The final quality standard is whether people can understand the content and its origin, not whether the audio can pass as an unlabelled human recording.
