ElevenLabs: eleven_flash_v2_5

Eleven Flash v2.5 is a high-speed text-to-speech model provided by ElevenLabs, specifically designed for real-time speech generation scenarios. According to the official documentation, this model has been optimized in terms of speech generation speed and system response time, and is currently one of the TTS models with the lowest latency. Flash v2.5 supports approximately 32 languages, and can handle up to about 40,000 characters in a single request, providing an extremely low latency performance of approximately 75 milliseconds (excluding network transmission and application layer delays). Therefore, it is highly suitable for applications that require high real-time performance, such as voice assistants, conversational AI, game interaction systems, and large-scale automatic speech generation tasks.
