microsoft/mai-voice-2.1-flash

Low-latency text-to-speech. MAI-Voice 2.1 Flash by Microsoft, routed through INFRO on a Microsoft account you connect — alongside every other provider you run. Microsoft bills you for it directly, on that account and at your own rate. INFRO adds routing, failover, request logs, cost attribution and policy around it, and takes no part of what you pay Microsoft.
