Android assistive communication app
AZ Weak Voice
Help turn speech or typed text into spoken output across supported languages, with optional authorized Personal Voice capability.
AZ Weak Voice was created around a simple but important problem: communication becomes much harder when speaking clearly or loudly is difficult. The app brings together Live Transcript, Type to Speak, Quick Phrases, multilingual speech-recognition and speech-output options, and optional authorized Personal Voice capability to give users multiple ways to communicate.
Communication support in one app
The app supports different communication needs rather than assuming one method works for everyone: recognizing spoken words, displaying transcript text, typing messages to be spoken, reusing quick phrases, or optionally generating authorized Personal Voice output.
✓ Live Transcript for speech recognition
✓ Type to Speak for typed speech output
✓ Quick Phrases for frequently used messages
✓ Optional authorized Personal Voice output
Core Features
Core communication features
Local recognition model
The app can download an in-app recognition model chosen by the user. Once the required model is available, supported speech-recognition processing can run locally.
Multilanguage support
Supports English, Chinese, Spanish, French, German, Italian, and Portuguese, plus bilingual English + Chinese recognition. Speech-output languages and voices can be selected from the available Android TTS and Personal Voice options.
Live Transcript controls
The established workflow includes recognition-model checking/downloading and manual completion through Finish & Transcribe. Generated speech can pause recognition and then resume automatically when configured.
Type to Speak
Save commonly used phrases for fast access when speaking repeatedly or typing a full message would be inconvenient.
Separate Android speech services
Gboard voice typing and Android system text-to-speech are separate Android/third-party services selected by the user. Their network or offline behavior depends on those services.
Core remains available
The core communication portion of AZ Weak Voice is designed to remain free. Personal Voice is an optional Pro capability rather than a requirement for the basic app.
PERSONAL VOICE PRO
Optional authorized Personal Voice output
Personal Voice is intended only for a reference voice the user owns or has explicit lawful permission to use.
What the Personal Voice workflow includes
✓ Personal Voice model download and management.
✓ Support for Multilingual Personal Voice and English & Chinese Personal Voice workflows.
✓ Personal Voice Manager for references and voice/profile management.
✓ Local Personal Voice generation after the required model files are available.
✓ A 7-day / 168-hour Personal Voice Pro trial.
✓ Optional Personal Voice Pro Lifetime purchase through Google Play.
✓ Restore Purchase and official Google Play promo-code redemption.
✓ No AZ Weak Voice user account required for trial, purchase, restore, or promo redemption.
Trial and Lifetime access
The dedicated privacy policy describes a 168-hour trial that is activated through the app with an online activation/recovery step. After activation, Personal Voice generation can continue offline during the remaining trial.
Personal Voice Pro Lifetime is handled through Google Play Billing. Verified entitlement can be restored through the app.
Personal Voice Pro also includes access to supported Personal Voice workflows, including Multilingual Personal Voice and English & Chinese Personal Voice options, depending on the selected voice setup.
Core communication features are separate from the Personal Voice Pro entitlement. Personal Voice Pro adds the voice-generation capability rather than turning the entire app into a paid product.
