Using Sayvai (Home Screen)

Categories and Phrase Icons

On Home, each category icon opens a page of phrase/action icons. When you tap an icon, Sayvai will play speech corresponding to that icon.

Default Icons vs Custom Icons

• Default icons: Included with the app.
• Custom phrase icons: Added by a Configurer under each category.

If you don't see an expected icon, verify you are in the correct category and confirm whether it is a default icon or a custom icon.

Modes (Mode Screen)

Sayvai supports two modes:

User Mode

This is the normal mode for day-to-day use:

• Browse categories
• Tap icons to speak

Configurer Mode

Configurer Mode is used to manage content:

• Add custom phrase icons under a selected category
• Delete custom phrase icons that were previously added

If you are helping a family member, caregiver, or patient, typically:

• Set up phrases in Configurer Mode
• Use the app daily in User Mode

Add a Custom Phrase Icon (Configurer Mode)

Important: Adding a custom phrase requires network connectivity.

1. Go to Mode
2. Switch to Configurer Mode
3. Navigate to the relevant category (Frequently Used / Day to day / Feelings / Activity)
4. Choose Add Custom Phrase (or the equivalent "+" action in your UI)
5. Enter the phrase text (the words you want Sayvai to speak)
6. Save the new custom phrase icon
7. Return to the category page and tap the new icon to test speech output

If "Add Custom Phrase" fails

Most common causes:

• No internet connection (Wi-Fi/cellular is off or unstable)
• Temporary backend/service issue
• Network restrictions (VPN, captive portal, restricted Wi-Fi)

Try:

• Turn Wi-Fi on (or switch to cellular)
• Confirm you can load a normal webpage outside the app
• Close and reopen Sayvai and try again

Delete a Custom Phrase Icon (Configurer Mode)

1. Go to Mode
2. Switch to Configurer Mode
3. Open the category containing the custom phrase icon
4. Select the custom phrase icon
5. Choose Delete (or trash/remove action)
6. Confirm deletion

Note: Default icons provided by the app may not be removable.

Settings Screen

Account (Login/Logout)

In Settings, you can:

• View your login information
• Log out
• Log in again (if needed)

If you cannot log in:

• Confirm internet connectivity
• Ensure you are using the correct email/account credentials

Font Size

You can adjust font size in Settings to improve readability. If buttons/labels look too small, increase font size here first.

Help Button

Use the Help button in Settings to open this Help page.

About / Version

Settings includes an About / Version section so you can identify the app version when reporting issues.

Voice Selection (1–4 default voices)

Sayvai supports selecting from 1–4 default voices.

• The available default voices are listed based on the user profile.

To change the voice:

1. Go to Settings
2. Open Voice (or equivalent section)
3. Select one of the available voices
4. Return to Home and test a phrase icon

If you do not see multiple voices, it may be because fewer voices are available for your profile.

1) No sound / low sound

Try in this order:

1. Increase the device Media volume (not ringer volume)
2. Disable Bluetooth (or confirm audio output is routed to the intended device)
3. Ensure the device is not in Do Not Disturb mode (some devices restrict audio)
4. Close other apps that may be using audio and try again
5. Restart the device

2) Custom phrase cannot be added

Checklist:

• Confirm Wi-Fi or cellular data is ON
• Switch networks (Wi-Fi ↔ cellular) and retry
• Close and reopen the app
• Try adding a short phrase (example: "Hello") to rule out edge cases

3) Custom phrase disappeared or is not visible

• Confirm you are in the correct category
• Confirm the phrase was added under the same user/account
• Ensure network is available, then restart the app

4) App is slow or freezes

• Restart the app
• Restart the device
• Ensure sufficient free storage
• Avoid running many apps in parallel on older tablets

5) App crashes

If the app crashes repeatedly:

• Restart device
• Update to the latest version (if applicable)
• Capture details for support:
  • Device model
  • Android version
  • Sayvai app version (Settings → About/Version)
  • Steps that reproduce the crash
