Picovoice Platform
Go Quick Start


Platforms

  • Linux (x86_64)
  • macOS (x86_64, arm64)
  • Windows (x86_64)
  • BeagleBone
  • NVIDIA Jetson Nano
  • Raspberry Pi (2, 3, 4)

Requirements

  • Picovoice Account & AccessKey
  • Go 1.16+
  • Windows only: a gcc compiler like Mingw in $PATH

Picovoice Account & AccessKey

Signup or Login to Picovoice Console to get your AccessKey. Make sure to keep your AccessKey secret.

Quick Start

Setup

  1. Download and install Go language .

  2. Install the Picovoice Go Package using the Go CLI:

go get github.com/Picovoice/picovoice/sdk/go/v2

Usage

Create an instance of Picovoice using a Porcupine keyword file (.ppn), and a Rhino context file (.rhn):

. "github.com/Picovoice/picovoice/sdk/go/v2"
. "github.com/Picovoice/rhino/binding/go/v2"
wakeWordCallback := func(){
// wake word detected
}
inferenceCallback := func(inference RhinoInference){
if inference.IsUnderstood {
intent := inference.Intent
slots := inference.Slots
// take action based on inferred intent and slot values
} else {
// handle unsupported commands
}
}
picovoice := NewPicovoice(
"${ACCESS_KEY}",
"${KEYWORD_FILE_PATH}",
wakeWordCallback,
"${CONTEXT_FILE_PATH}",
inferenceCallback)
err := picovoice.Init()

Pass in frames of audio to the .Process function:

func getNextAudioFrame() []int16 {
// ..
}
for {
audioFrame := getNextAudioFrame()
err := picovoice.Process(audio_frame)
}

Release resources explicitly when done with Picovoice:

picovoice.Delete()

Custom Wake Words & Contexts

Create custom wake word and context files using the Picovoice Console . Download the custom models (.ppn and .rhn) and pass them into the NewPicovoice constructor.

Non-English Languages

Use the corresponding model file (.pv) to process non-English wake words and contexts. The model files for all supported languages are available on the Porcupine GitHub repository and the Rhino GitHub repository .

Pass in model files using the PorcupineModelPath and the RhinoModelPath parameters to change the language:

picovoice := NewPicovoice(
"${ACCESS_KEY}",
"${KEYWORD_FILE_PATH}",
wakeWordCallback,
"${CONTEXT_FILE_PATH}",
inferenceCallback)
picovoice.PorcupineModelPath = "${PORCUPINE_MODEL_FILE_PATH}"
picovoice.RhinoModelPath = "${RHINO_MODEL_FILE_PATH}"
err := picovoice.Init()

Demo

For the Picovoice Go SDK, we offer demo applications that demonstrate how to use the Picovoice Platform on real-time audio streams (i.e. microphone input) and audio files.

Setup

Clone the Picovoice GitHub Repository :

git clone --recurse-submodules https://github.com/Picovoice/picovoice.git

Usage

Use the -h flag to see the usage options for the demo:

cd picovoice/demo/go
go run micdemo/picovoice_mic_demo.go -h

Ensure you have a working microphone connected to your system and run the following command to make inferences based on the given keyword and context files:

go run micdemo/rhino_mic_demo.go -access_key "${ACCESS_KEY}" \
-keyword_path "${KEYWORD_FILE_PATH}" \
-context_path "${CONTEXT_FILE_PATH}"
