Cast an AI voiceover, then check the name

Audition three AI voices on your own script, compare pronunciation in the full read, and keep the cast, rules and earlier takes together in Voyager.

A convincing voice can still say your name wrong. Audition a real sentence, establish its pronunciation, then check the full read before using it in a product demo, workshop announcement or narrated walkthrough.

We tried Eleven v4 for a short invitation to Serein, a fictional ceramics studio. Casting was straightforward. Getting the name to stay consistent took more work.

Listen: three original Eleven v4 auditions, before pronunciation correction. Same script and direction; playback levels matched.
Description / transcript

Sarah, George and Lily each say: At Serein, we turn a lump of clay into the cup you reach for every morning.

Audition your words

Voice-library samples tell you what a narrator can sound like. Your script tells you whether that narrator fits the job.

Prompt
Cast a warm, natural English narrator for a small ceramics workshop. Inviting, not breathy or hard-selling.

Have three distinct voices read this exact sentence with the same direction:
“At Serein, we turn a lump of clay into the cup you reach for every morning.”

Start with Natural delivery and a gentle, warm tone. Compare the pacing, the brand name and whether the invitation sounds like someone you would want to learn from.

We chose George's quieter, grounded delivery. Sarah sounded more commercial; Lily leaned breathier. Those are choices for this invitation, not a ranking of the voices.

Check the name in the full read

For this invented studio, we wanted suh-REN, with stress on the second syllable. A respelling rule produced that stress in a short audition. The complete read brought back the first-syllable stress, despite using the same saved rule. Several sentence repairs did not give us a complete, consistently pronounced result.

Keep Serein in the script and captions. Put the sound-alike spelling in a pronunciation rule, then hear it in context. A correctly spelled transcript cannot tell you which syllable was stressed.

Original v4 read, then final v3 read. Same voice and written sentence, different pronunciation approach. Playback levels matched.
Description / transcript

Both reads say: At Serein, we turn a lump of clay into the cup you reach for every morning. The original stresses the first syllable of the name; the final read stresses the second.

Keep the production together in Voyager

With a media account connected, Voyager's Voice panel saves the script, cast, delivery, pronunciation rules and takes. We could change the pronunciation approach while keeping George and the written invitation.

Prompt
Keep George, the written script and the warm delivery. The name should sound suh-REN, with stress on REN. Check which pronunciation controls the model supports. Show what needs to be re-recorded and the cost before generating. Preserve the original so we can compare.

For the final take, we switched to v3 and used IPA /səˈrɛn/ in the saved pronunciation rule. That read gave us the intended second-syllable stress and the complete invitation. Hear the comparison above; one name is not a general model ranking.

Changing models required a whole new take: a repair stays on its parent's model. Voyager kept the earlier takes and saved casting decisions, so we did not have to rebuild the production or overwrite the original.

17-second desktop walkthrough of the saved cast, pronunciation rule and chosen take. Brief cast hold; generation waits omitted. Silent demonstration.
Description / transcript

In the actual Voyager desktop app, George remains selected alongside the earlier auditions. The Script panel stores Serein with its pronunciation rule. The Takes panel plays the approved v3 full read while retaining the earlier takes.

Before choosing a take, listen to the complete read. Names, acronyms and unfamiliar terms deserve a second pass, even when the first audition worked.
