# Deepgram Java SDK v0.10.0 removes SpeakV2Speed and AURA2PERSEO\_IT constants

Markdown version of <https://harbyn.com/changes/deepgram/2026-09-14-sdk-releases-6>.

Breaking change - Deepgram. medium severity. In effect.

Java SDK v0.10.0, a pre-1.0 release, removes SpeakV2Speed and its named speed constants, plus the AURA2PERSEO\_IT model constants and visitor methods for a model the API never served. Set speed with a numeric value such as .speed(1.05) and use a supported Speak V1 model. The release also adds sendForceEndTurn(...), Agent Flux TTS expressivity, and the Flux TTS speed range of 0.5 through 1.5.
