Anti-Vocale 1.15.0

Anti-Vocale transcribes voice messages from WhatsApp, Telegram, and other messaging apps directly on your Android device. All processing happens on-device: your audio never leaves your phone. It works on recorded calls and meetings too: recordings of any length are split and stitched automatically (up to two hours on the streaming path), a failed run keeps the transcript it produced, and long transcripts can be exported as subtitles (SRT, VTT) or timestamped text, with sentence-level timing on streaming models.

BUILT-IN MODELS

- Parakeet TDT (recommended): fast, 25 European languages. Two variants: high-quality (862MB) or compact (464MB)
- Whisper Turbo: 99 languages, balanced speed and quality
- Whisper Distil Italian: best Italian quality, tuned for voice messages
- Whisper Medium / Small: more accuracy or smaller download
- Nemotron 3.5 streaming: text appears in real time while it decodes, 45 languages
- Qwen3-ASR: compact, 59 languages
- GigaAM v3: Russian, very small and fast
- Gemma 4 / 3n (LiteRT): multimodal AI with customizable prompts

BRING YOUR OWN MODELS

Import custom transcription models from a folder on your phone or from a link: Whisper fine-tunes, CTC models, SenseVoice and other sherpa-onnx architectures. Files are integrity-checked on import, split-file models are supported, and every imported model gets its own share target. Ideal for languages the built-in models don't cover.

FEATURES

- Share voice messages from any app via the Android share sheet
- Smart notifications: one-tap copy, share back, page through long transcripts without opening the app
- Auto-copy to clipboard and auto-save transcripts to a folder you pick (Drive, Syncthing, ...)
- Video file transcription (audio track extracted)
- Real-time progressive text with streaming models
- Per-app notification preferences
- Transcription log with search and swipe actions
- Silence stripping and parallel chunk processing for speed
- Neural acceleration (NNAPI) on supported devices, with automatic CPU fallback

- Scheduled folder watch: transcribe new audio files in folders you choose automatically (on Android 11+, even a messaging app's media folder)
- Remote offload (experimental, off by default): delegate long transcriptions to your own OpenAI-compatible server
- Open Transcribe provider (experimental): apps that speak the open contract, like Forkgram, turn Anti-Vocale into their inline voice transcriber

PRIVACY

No network needed after download, no accounts, no data collection, no ads, no tracking. By default the audio never leaves your phone; the only exception is the optional Remote offload feature, which sends audio solely to the server address you configure and stays off unless you turn it on.
