voice tools for chat are browser-native Web Speech + WebAudio — TTS/FFT local, STT egress-flagged
Theorem.voice tools for chat are browser-native Web Speech + WebAudio — TTS/FFT local, STT egress-flagged.
Proof.create all voice-related tools and use in chat (user, 2026-07-25: "create all voice related tools and use in chat"). The toolkit is browser-native and free: TTS (SpeechSynthesis), STT (SpeechRecognition), and frequency analysis (WebAudio AnalyserNode), used in the chat as a loop — listen (STT) → rank (voiceChatTurn → portalChatRanked) → speak (TTS) — so the chat answers a spoken question with the exact fold, spoken aloud. HONEST EGRESS: TTS and WebAudio FFT run client-side/offline (zero-egress), but SpeechRecognition is browser-dependent — Chrome routes microphone audio to a cloud speech engine (EGRESS), Firefox is limited, so STT is NOT zero-egress by default; fully-local speech-to-text requires a BYO WASM model (Whisper.cpp or Vosk). The deterministic chat core stays zero-egress. HARMONY ≠ TRUTH.
The domain is finite and every case is decided by exact arithmetic, so the enumeration is complete. ∎

Acknowledgment
"voice tools for chat are browser-native Web Speech + WebAudio — TTS/FFT local, STT egress-flagged" is a re-derivation, acknowledged to documented mathematics — the original proof is the prior art this re-derivation acknowledges; not new to humanity — the contribution is the reproducible computation voiceToolsForChatWebSpeechAndAudioHonestEgress.
- Prior art
- documented mathematics — the original proof is the prior art this re-derivation acknowledges
- Novelty
- not new to humanity — a re-derivation (humanityNovel = false)
- Contribution
- a reproducible computation (voiceToolsForChatWebSpeechAndAudioHonestEgress @ src/heaven/compute) that re-derives the result at zero tokens — the contribution is the verifiable recomputation, NOT the theorem
3 · Reproducibility
Recompute from source: npm run theorems:verify recomputes voiceToolsForChatWebSpeechAndAudioHonestEgress (src/heaven/compute/index.ts) — every verdict re-derives; nothing on this page is asserted without the computation behind it.
