Naming changes from August and September 2026. Old names and identifiers below describe those transitions. For a current upgrade, start with the upgrade guide and compatibility matrix.
Quail -> Quail Multi Speaker
In September 2026, Quail became Quail Multi Speaker to distinguish the general-purpose model from Quail Voice Focus.
Quail Voice Focus was not part of this naming change and retains the
quail-vf-* naming pattern. This does not mean every version remains supported; see deprecated models for removed Voice Focus IDs.
VAD: Quail VAD -> VAD -> VAD Multi Speaker
The voice activity detection (VAD) models dropped the Quail prefix in August 2026. In September, the general-purpose model gained an-ms- infix to distinguish VAD Multi Speaker from VAD Voice Focus.
Current rename
VAD Voice Focus was not part of this step and keeps its
vad-vf-2.0-s-16khz ID.
August transition: these intermediate names precede the September rename above.
VAD moved from 2.0 to 2.1 in this step, so it was both a rename and a newer model version. VAD Voice Focus stayed at 2.0.
Rook -> Rook Multi Speaker
In September 2026, the perceptual speech enhancement models became Rook Multi Speaker. Their IDs gained an-ms- infix.
Some old model IDs on this page are no longer supported by the current core SDK. Update to the current IDs above. For models that have been removed, see deprecated models for their last supported core SDK versions.
