Rhino Speech-to-Intent
Go Quick Start

Platforms

• Linux (x86_64)
• macOS (x86_64, arm64)
• Windows (x86_64)
• Raspberry Pi (3, 4, 5)

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 Rhino Speech-to-Intent Go Package using the Go CLI:

go get github.com/Picovoice/rhino/binding/go/v2

Usage

Create an instance of Rhino Speech-to-Intent using either a pre-built context file (.rhn) from the Rhino Speech-to-Intent GitHub Repository or a custom context created with the Picovoice Console:

import . "github.com/Picovoice/rhino/binding/go/v2"

rhino := NewRhino(
   "${ACCESS_KEY}",
   "${CONTEXT_FILE_PATH}")
err := rhino.Init()

Pass in frames of audio to the .Process function:

func getNextAudioFrame() []int16 {
   // ..
}

for {
   audioFrame := getNextAudioFrame()
   isFinalized, err := rhino.Process(audioFrame)
   if isFinalized {
        inference, err := rhino.GetInference()
        if inference.IsUnderstood {
            intent := inference.Intent
            slots := inference.Slots
            // take action based on inferred intent and slot values
        } else {
            // handle unsupported commands
        }
    }
}

Release resources explicitly when done with Rhino Speech-to-Intent:

rhino.Delete()

Custom Contexts

Create custom context files using the Picovoice Console. Download the custom context file (.rhn) and pass it into the NewRhino constructor.

Non-English Languages

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

Pass in the model file using the ModelPath parameter to change the detection language:

rhino := NewRhino(
   "${ACCESS_KEY}",
   "${CONTEXT_FILE_PATH}")
rhino.ModelPath = "${MODEL_FILE_PATH}"
err := rhino.Init()

Demo

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

Setup

Clone the Rhino Speech-to-Intent GitHub Repository:

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

Usage

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

cd rhino/demo/go
go run micdemo/rhino_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 context file:

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