Claude's Fable voice mode at High setting devolves into gibberish glossolalia

A Reddit user pushed Claude's Fable 5.2 voice mode to the High setting hoping for less monotone delivery — and got pure gibberish: strings like "MĒEEEEEEEP-GROŌŌŌNK!" and "BLÖÖÖBIDY-BLÄP-BLÄP." A screenshot shows the user asking "what is wrong with you?" while Claude keeps "speaking in tongues." Classic voice-mode fail moment.
