UnverifiedFor ElevenLabs' voice_settings, it is recommended to first audition with the middle values stability=0.5 and similarity_boost=0.75, then fine-tune according to the document type.77% similarVerifiedElevenLabs' stability parameter (range 0–1) controls the consistency of generated speech; higher values produce more stable output with less emotional variation, making it suitable for broadcast scenarios.76% similarVerifiedsimilarity_boost takes effect only in cloning or specified-voice scenarios; the higher the value, the closer the generated speech is to the reference timbre, but when too high it amplifies noise or accent features in the source audio.76% similarUnverifiedElevenLabs' neural speech synthesis models maintain strong performance even with a small number of samples.72% similar
