PicovoiceVue type.

• state object : PicovoiceVue internal states.
  • wakeWordDetection PorcupineDetection | null : A state that is updated when the wake word has been detected.
  • inference RhinoInference | null : A state that is updated when an inference has been made.
  • contextInfo string | null : A state that updates when Rhino context info is available. Shows the list of intents, which expressions map to those intents, as well as slots and their possible values.
  • isLoaded boolean : A state indicating whether the engine is initialized successfully.
  • isListening boolean : A state indicating whether the webVoiceProcessor is passing audio to the engine.
  • error string | null : A string expression of the error.
• init (...) => Promise<void> : A method to initialize the internal PicovoiceWorker. See init.
• start () => Promise<void> : A method to start processing the audio. See start.
• stop () => Promise<void> : A method to stop processing the audio. See stop.
• release () => Promise<void> : Releases resources acquired by PicovoiceVue. See release

usePicovoice

usePicovoice(): PicovoiceVue { }

Vue reactive API for Picovoice SDK.

Returns

• PicovoiceVue: States and functions for Picovoice Vue binding.

init()

async function init(
  accessKey: string,
  keyword: PorcupineKeyword,
  porcupineModel: PorcupineModel,
  context: RhinoContext,
  rhinoModel: RhinoModel,
  options: PicovoiceOptions = {}
): Promise<void>

Initializes the internal PicovoiceWorker. Sets state.isLoaded state to true if successful.

Parameters

• accessKey string : AccessKey obtained from Picovoice Console.
• keyword PorcupineKeyword : A Porcupine keyword. Can be provided as a built-in, base64 or a hosted .ppn file.
• porcupineModel PorcupineModel : Contains the model parameters that are used to initialize the Porcupine engine. Model can be encoded in base64 or can be stored in a .pv file in a public directory.
