Voca is designed for the default GrapheneOS (nprofile…xdyf) text to speech engine.
You can try Sherpa, a good FOSS engine with multiple different mods.
What phone and provider app are you using?
Long time between sentences could mean not enough processing power to generate sentences, or it could be a bug in voca.
In the voca settings you can activate recording diagnostics and include text, then load a demo text, play it, and share the logs via nostr DM, I'll have a look. https://zapstore.dev/apps/naddr1qqvx7un89emk76r9d3kx2u3k8yh8garnv4hxw6twv5q3samnwvaz7tmjv4kxz7fw0fshqum5daex2tnyv4mqygrceeh65u3xgwrjsnny0wnf8zv4wd0v3374ckn9wdl92yc0qf3s05psgqqq0c9sx6lewv
