How ElevenLabs used a blind test to launch Eleven v4
ElevenLabs launched Eleven v4 on Oct 15, 2026 with a blind test. It tested the voice model against other models in eight languages and said listeners picked it as more expressive in every test. A blind test is proof buyers trust more than a company claim, and the result fits in one line.
