Welcome to Davoice Expo Wake Word / hotword / Keywords Detection – Wake words and keyword detection solution designed by DaVoice.io.

About this package:

This is a "wake word" package for Expo. A "wake word" is a keyword that activates your device, like "Hey Siri" or "OK Google". "Wake Word" is also known as "keyword detection", "Phrase Recognition", "Phrase Spotting", “Voice triggered”, “hot word”, “trigger word”

It also provide Speech to Intent. Speech to Intent refers to the ability to recognize a spoken word or phrase and directly associate it with a specific action or operation within an application. Unlike a "wake word", which typically serves to activate or wake up the application, Speech to Intent goes further by enabling complex interactions and functionalities based on the recognized intent behind the speech.

For example, a wake word like "Hey App" might activate the application, while Speech to Intent could process a phrase like "Play my favorite song" or "Order a coffee" to execute corresponding tasks within the app. Speech to Intent is often triggered after a wake word activates the app, making it a key component of more advanced voice-controlled applications. This layered approach allows for seamless and intuitive voice-driven user experiences.

Wake word generator

Create your "custom wake word""

In order to generate your custom wake word you will need to:

• Create wake word mode: Contact us at [email protected] with a list of your desired "custom wake words".

  We will send you corresponding models typically your wake word phrase .onnx for example:

  A wake word *"hey sky" will correspond to hey_sky.onnx.

• Add wake words to Android: Simply copy the new onnx files to:

  android/app/src/main/assets/*.onnx

• Add Wake word to IOS Copy new models somewhere under ios/YourProjectName.

  You can create a folder ios/YourProjectName/models/ and copy there there.

  Now add each onnx file to xcode making sure you opt-in “copy if needed”.

• In React/JS code add the new onnx files to your configuration

  Change:

    // Create an array of instance configurations

    const instanceConfigs:instanceConfig[] = [
  
      { id: 'need_help_now', modelName: 'need_help_now.onnx', threshold: 0.9999, bufferCnt: 3 , sticky: false },
  
    ];
  
    To:
  
    // Create an array of instance configurations
  
    const instanceConfigs:instanceConfig[] = [
  
      { id: 'my_wake_word', modelName: 'my_wake_word.onnx', threshold: 0.9999, bufferCnt: 3 , sticky: false },
  
    ];
  
    For example if your generated custom wake word" is "hey sky":
  
    // Create an array of instance configurations
  
    const instanceConfigs:instanceConfig[] = [
  
      { id: 'hey sky', modelName: 'hey_sky.onnx', threshold: 0.9999, bufferCnt: 3 , sticky: false },
