Eleven Flash v2.5 is designed for low-latency text-to-speech output. ElevenLabs lists about 75 ms latency, 32 languages, and up to 40,000 characters per request.
Flash v2.5 normalizes phone numbers, dates, and currencies less reliably by default than slower models. The documentation lists normalization as an Enterprise option. Its low latency does not remove that documented boundary for numeric text.
