Quick answer
Choose this voice option if it sounds clear on your phone and the memory, storage, and battery cost make sense for how long you listen.
The best voice is not always the biggest model. A lighter voice that starts quickly and runs smoothly can be better for everyday reading.
Compare voices with the same paragraph
Use the same 30 to 60 seconds of text for each voice. Keep the speed the same.
Listen for clear words, natural pauses, stable volume, and whether the voice becomes tiring after a few minutes.

It uses more storage and resources than a system voice.
Piper voices are separate local downloads. Readream Pro guidance uses about 2.5 GiB usable RAM as a practical starting point and about 64 MiB per voice.
Use the voice for a full chapter
A one-sentence demo can hide annoying pronunciation or rhythm problems.
Listen for at least one real section before deciding whether to keep a downloaded voice.
Keep a fallback voice
If a heavy voice becomes slow or drains too much battery, switch to an Android system voice.
