Quick Start

Setup

1. Install Node.js.

2. Install the Falcon Speaker Diarization Web package:

npm install @picovoice/falcon-web

Usage

Put the model file in the project's public directory or generate a base64 model using the built-in script:

npx pvbase64 -i ${FALCON_PARAMS_PATH} -o ${OUTPUT_FILE_PATH}

Create a FalconWorker instance using a base64 model or a model hosted in a public directory:

import { FalconWorker } from "@picovoice/falcon-web"
import falconParams from "${FALCON_PARAMS_BASE64_PATH}";

const falcon = await FalconWorker.create(
  "${ACCESS_KEY}",
  {
    base64: falconParams,
    // or
    publicPath: "${MODEL_RELATIVE_PATH}"
  }
);

Perform diarization (sample rate of 16 kHz, 16-bit linearly encoded and 1 channel):

function getAudioData(): Int16Array {
  // get audio
  return new Int16Array();
}

const { segments } = await falcon.process(getAudioData());

Release resources explicitly when done with Falcon Speaker Diarization:

await falcon.release()

Segments

Falcon Speaker Diarization returns an array of segments. Each segment has the following properties:

• Start Time: Indicates when the segment started. Value is in seconds.
• End Time: Indicates when the segment ended. Value is in seconds.
• Speaker Tag: A non-negative integer identifying unique speakers.
