OpenWhisperer 1.6.0 — Antigravity & Pi, voice personas, mid-turn speaking
What's New in 1.6.0
- Two more agents — Antigravity & Pi. Spoken replies now work beyond Claude Code and Codex in the Antigravity CLI (
agy) and Pi. Pick your agent in the Setup card and Auto-Apply wires it up: Claude Code, Codex, and Antigravity get a hook plus aspeaktool; Pi gets a drop-in extension. - Voice personas. Pick a voice with a national accent and the reply is written to match its character — the British voice turns dry and deadpan, the Italian voice warm and expressive, the Japanese voice courteous and understated, and so on across nine accents. It colors tone only; it never changes the facts.
- Mid-turn speaking. Replies are spoken through an in-app
speaktool the agent calls, so speech can start mid-turn instead of only after the whole reply lands. (Pi uses an equivalent extension.) - Queue spoken replies (new) — an option to let replies queue and play in order instead of the newest cutting off the last.
- Adjustable speaking speed. A Speed slider in Voice Settings sets how fast replies are spoken (0.7×–1.5×, default 1.1×). Per-project override via
OW_TTS_SPEED. - Scalable overlay. The floating overlay has a resize grip — drag up to step the transcript from 3 → 2 → 1 lines, then to a waveform-only pill; the size is remembered.
- Simpler Response modes. The little-used "when Text" option is gone; Response is now when Voice (dictated turns only, the default) or Always.
- Fixes. Invalid voice names from the model are ignored (falls back to your voice); the transcription overlay takes the first click even when the app is in the background (click any line to copy it); the Permissions rows stay visible in the menu.
Install
Download OpenWhisperer-1.6.0.dmg below and drag it to Applications. The app isn't signed with a paid Apple Developer certificate, so allow it to run:
xattr -cr /Applications/OpenWhisperer.app
On first launch macOS asks for Microphone, Accessibility, and Speech Recognition permissions, and the models download (~1.7 GB) and compile for the Neural Engine (~1–2 min, one-time).
Setting up voice for your agent: open the Setup card, pick your agent, and hit Auto-Apply. Then restart your agent (Claude Code / Codex / Antigravity / Pi) so it loads the speak tool — in Claude Code you can confirm with /mcp (you should see OpenWhisperer connected). Spoken replies won't play until the agent has loaded the tool.
