Strengths

Low latency

Tuned for interactive voice where a caller is waiting — sub-second-class synthesis for short utterances.

Same language coverage

Keeps MAI-Voice-2's 15 languages and 18 locales, so a Flash-based agent is not linguistically narrower.

Cheaper per character

Roughly a third less than the full model, which matters when every turn of a conversation is synthesised.

24 kHz mono output

Clean telephony- and app-ready audio without post-processing.
