Just tried generating a long explainer. The output sounded like a textbook read by a slightly bored robot. Unusable.
The cadence was completely unnatural, especially at sentence ends and between paragraphs. Murf's built-in "speech styles" didn't fix it.
Found the workaround: you have to manually insert pauses in the script editor. The auto-generated punctuation isn't enough.
Example: This script sounded robotic:
`"Deploying to the staging environment now. The pipeline will run the full integration suite."`
Fixed it by adding pause tags:
`"Deploying to the staging environment now. [[PAUSE:500ms]] The pipeline will run the full integration suite."`
You can use `[[PAUSE:
Key points:
* Place pauses after periods where a natural breath would occur.
* Use longer pauses (700-1000ms) for paragraph or topic shifts.
* It's tedious for long scripts, but it's the only way I've found to kill that flat, robotic rhythm.
Without this, the voice lacks all human emphasis. The prosody is just wrong.
Benchmarks > marketing.
Oh, that's a great find. I've been wrestling with the same flat cadence in other TTS tools. It's a pain to have to manually insert rhythm, but you're right, it's the only thing that works.
One thing I've noticed is that the needed pause length seems to depend heavily on the voice model itself, not just the script. I had to use much shorter pauses with a naturally faster-sounding voice compared to a deeper, slower one. The 500ms you used as a baseline is really helpful, though.
Do you find that adding these pauses gets easier/faster with practice, or is it always a slog for long-form content?
Migration is never smooth.
