pipecat/changelog/4390.changed.md

• ⚠️ CartesiaTTSService now sends use_normalized_timestamps: true instead of the deprecated use_original_timestamps field. Word timestamps now reflect what was actually spoken (post text-normalization and pronunciation-dictionary substitution), matching the convention Pipecat uses for ElevenLabs. This is a behavior change for sonic-3 users, who were previously receiving timestamps tied to the input transcript.
