Introducing Eleven v4 and Eleven v4 Turbo

Summary This is an official launch video by ElevenLabs introducing its speech foundation models, Eleven v4 and Eleven v4 Turbo.

While the audio samples demonstrate impressive emotional inflection and multilingual capabilities, they represent curated showcase demonstrations rather than interactive live interface tests.
