Platforms

• Linux (x86_64)
• macOS (x86_64, arm64)
• Windows (x86_64)
• NVIDIA Jetson Nano
• Raspberry Pi (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 Cheetah Go Package using the Go CLI:

go get github.com/Picovoice/cheetah/binding/go

Usage

Create an instance of the Cheetah engine:

import . "github.com/Picovoice/cheetah/binding/go"

cheetah = NewCheetah("${ACCESS_KEY}") // AccessKey provided by Picovoice Console (https://console.picovoice.ai/)
err := cheetah.Init()
if err != nil {
    // handle init err
}
defer cheetah.Delete()

Transcribe audio:

func getNextFrameAudio() []int16{
    // get audio frame
}

for {
  partialTranscript, isEndpoint, err = cheetah.Process(getNextFrameAudio())
  if isEndpoint {
    finalTranscript, err = cheetah.Flush()
  }
}

When done be sure to explicitly release the resources using cheetah.Delete().

Demo

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

Setup

Clone the Cheetah repository from GitHub using HTTPS:

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

Usage

To see the usage options for the demos, use the -h flag:

cd cheetah/demo/go
go run micdemo/cheetah_mic_demo.go -h

Ensure you have a working microphone connected to your system and run the following command to perform live speech-to-text:

go run micdemo/cheetah_mic_demo.go -access_key "${ACCESS_KEY}"
