Rhino Speech-to-Intent
React API

API Reference for the Rhino React SDK (npmjs).

useRhino()

function useRhino()

React Hook for Rhino Speech-to-Intent engine

Returns

• inference RhinoInference | null : A state containing the inference.
• contextInfo string | null : Context information.
• 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 and Rhino is listening for an utterance.
• errorMessage string | null : A string expression of an error when an error is present.
• init () => Promise<void> : A method to initialize Rhino. See init().
• process () => Promise<void> : A method to start processing audio. See process().
• release () => Promise<void> : A method to cleanup resources acquired by Rhino. See release().

init()

async function init(
  accessKey: string,
  context: RhinoContext,
  model: RhinoModel,
  options: RhinoOptions = {}
): Promise<void>

Initializes the Rhino Speech-to-Intent engine. Sets isLoaded to true on success.

Parameters

• accessKey string : AccessKey obtained from Picovoice Console.
• context RhinoContext : Object containing Rhino context data.
• model RhinoModel : Object containing Rhino model data.
• options RhinoOptions : Optional configuration arguments.

process()

async function process(): Promise<void>

Puts the RhinoService in an active isListening state. The process function initializes WebVoiceProcessor. Rhino will then listen and process frames of microphone audio until it reaches a conclusion, then return the result via the inference state. Once a conclusion is reached Rhino will enter a paused state. From the paused state call process again to detect another inference.

release()

async function release(): Promise<void>

Releases resources acquired by the Rhino React SDK.
