Turbo v2.5 arrived in July 2024 and extended ElevenLabs' low latency tier from English to 32 languages, making Hindi, French, Spanish, Mandarin and more roughly three times faster than before, with English itself about 25 percent faster. ElevenLabs has since positioned Flash v2.5 as its successor. It was the strongest ElevenLabs model in blind listening tests while it competed on the Humanness Index™, and it is now retired from the arena in favor of one entry per active family.
Turbo v2.5 brought 32 languages to the low latency tier when it launched in July 2024. In our 50 trial streaming benchmark it returned first audio in a median of 265 ms.
Listeners hear Turbo v2.5 against another model in a blind head to head round, both voices reading the same customer support prompt from the same cloned source voice, and they pick whichever sounds more human. Its Humanness score derives purely from those votes.
How does Turbo v2.5 compare to Flash v2.5?
Flash v2.5 is faster in our measurements (197 ms vs 265 ms median TTFB) and ElevenLabs recommends Flash for new real time builds, but Turbo v2.5 posted the stronger humanness showing in blind tests while it competed.
