Example for streaming speech to text

For this example, we'll use the streaming SpeechToText grpc service to transcribe an audio file with VNG Cloud Speech Text AI.

Requirements

• Golang 1.22 or above
• A VNG Cloud Account
• Pakage pkg-config and portaudio

Setup

1. Enable the Speech-to-Text API
2. Create a service account with action ai-stt-tts:StreamingSpeechToText permission and download the service account key

Installation

git clone https://github.com/vngcloud/stt-streaming-example.git

The proto file is located at proto/stt.proto. You can generate the gRPC client by running the following command:

cd proto
./generate.sh
cd ../

For build and run the example

#file streaming example
go build -o file ./examples/file/main.go

#mic streaming example
go build -o mic ./examples/mic/main.go
