Apple is rolling out a "brand new voice experience" for Siri AI, letting users customize how the voice assistant sounds. The update brings more expressive voices and improved systemwide dictation accuracy to devices supporting Apple's most advanced on-device model. Users can adjust both expressiveness and pace through a new UI with sliders for a more personalized interaction.

The updated dictation engine captures speech as polished text, automatically handling capitalization, punctuation, and formatting in real time. Apple claims improved speech understanding means users can speak naturally and trust their words will appear accurately. As of the developer beta 1, American remains the sole voice option, though more options likely coming.

This customization represents a significant shift in how users interact with voice assistants, moving beyond standardized options to personalized experiences. The focus on natural speech understanding addresses long-standing frustration with assistants that couldn't accurately capture intent or nuance. Dictation accuracy improvements directly impact productivity for those who rely on voice input.
