1. Choose by the job, not a stereotype
Start by describing what the voice must help the audience do. A product demo may need clear timing around steps. A concise promotion may need energy without swallowing the offer. A tutorial may need enough space for viewers to follow the interface. These are functional requirements, not personality labels.
Avoid deciding that a particular gender, age impression, or accent is automatically more trustworthy. Test the delivery against the message and audience. If regional pronunciation matters, state that requirement explicitly and have an appropriate listener review it.
2. Build one fair audition script
A useful audition includes the product name, one number or date, a normal sentence, a short action line, and any difficult term that will recur. Keep it short enough to compare several times without listener fatigue. Use the exact same punctuation and settings for every candidate during the first pass.
Do not use an existing audition clip as proof of how voices compare if the scripts differ. A transparent, reproducible public comparison should publish the shared transcript, settings, date, and unprocessed samples at matched loudness.
Meet the LynxTTS voice library. Choose a voice for your product demo, generate the narration, and compare the result before you publish. Use the version that sounds clearest with your visuals.Use this only as a starting point; include the real names and terms from your project.
3. Treat style labels as starting points
| Starting style | Try it for | Listen for |
|---|---|---|
| Conversational | Creator demos, onboarding, direct explanation | Natural phrasing without losing key terms |
| Ad-read | Short offers, launches, high-energy demonstrations | Energy that stays clear and does not sound forced |
| Professional | Tutorials, company explainers, structured updates | Authority without stiffness or excessive distance |
| Narrative | Stories, documentaries, longer context | Pacing, continuity, and controlled emphasis |
The table suggests candidates to test. It is not a universal ranking, and the same voice can work in more than one role.
4. Score what you can actually hear
- Pronunciation: names, brands, numbers, abbreviations, and specialist terms.
- Clarity: important words survive phone speakers and normal background noise.
- Pace: the viewer has time to understand the visual evidence.
- Tone fit: the delivery supports the scene without sounding theatrical by accident.
- Consistency: volume, pace, and character remain stable across paragraphs.
- Editability: pauses and sentence boundaries give the editor usable cut points.
5. Test inside the real video mix
A voice that sounds impressive alone can lose clarity under music, sound effects, or a busy screen recording. Put the candidate into a rough edit and listen at ordinary phone volume. Lower competing audio first; do not solve every problem by making the narration louder.
Once you decide, save a short voice brief: use case, voice name, speed, pronunciation notes, loudness target, and one approved reference clip. That gives future videos consistency while still allowing a new audition when the job changes.
