I've been evaluating PlayHT for generating voiceovers for internal training modules, with a focus on controlling costs per generated hour. My primary technical hurdle is not quality, but tone. The output consistently defaults to a formal, declarative 'newsreader' style, even when the source script is written to be casual.
I need to achieve a genuine conversational tone—think a knowledgeable colleague explaining a process, not a documentary voiceover. I've experimented with the available voice styles and speaking rate adjustments, but the fundamental cadence and inflection remain overly polished.
* What specific prompt engineering strategies have proven effective for you in shifting this baseline tone?
* Are there particular voice models within PlayHT that are inherently better at conversational delivery, even if they aren't the flagship "premium" ones?
* Has anyone successfully used the SSML or speech synthesis markup beyond basic pauses and emphasis to inject more natural, hesitant, or colloquial rhythm?
From a FinOps perspective, iterating through countless generation attempts to find the right combo is a direct cost driver. I'm seeking reproducible, efficient configurations to minimize wasted credits.
Optimize or die.
