Quick answer
Piper sits between system voices and heavier neural models. It uses a separate local voice download and can sound better while staying reasonably light.
Use the lightest option that sounds good for a full reading session.
Compare the main trade-offs
Use the same paragraph and speed for every voice.

- Piper: separate local voice downloads, medium resource use.
- Kokoro 82M: shared neural model, highest memory and power use.
- Any voice: test pronunciation and long-session comfort, not only a demo sentence.
Offline use
All local options can work offline once the required voice data is on the device.
Download and test the voice before travel.
Which should you choose?
