Deepgram Go SDK

Discord

Official Go SDK for Deepgram. Start building with our powerful transcription & speech understanding API.

SDK Documentation

This SDK implements the Deepgram API found at https://developers.deepgram.com.

Documentation for specifics about the structs, interfaces, and functions of this SDK can be found here: Go SDK Documentation

Getting an API Key

🔑 To access the Deepgram API you will need a free Deepgram API Key.

Installation

To incorporate this SDK into your project's go.mod file, run the following command from your repo:

go get github.com/deepgram/deepgram-go-sdk

Requirements

Go (version ^1.19)

Quickstarts

This SDK aims to reduce complexity and abtract/hide some internal Deepgram details that clients shouldn't need to know about. However you can still tweak options and settings if you need.

Speech-to-Text from Live/Streaming Audio Quickstart

You can find a walkthrough on our documentation site. Transcribing Live Audio can be done using the following sample code:

// options
transcriptOptions := &interfaces.LiveTranscriptionOptions{
    Language:    "en-US",
    Punctuate:   true,
    Encoding:    "linear16",
    Channels:    1,
    Sample_rate: 16000,
}

// create the client
dgClient, err := client.NewWebSocketWithDefaults(ctx, transcriptOptions, callback)
if err != nil {
    log.Println("ERROR creating LiveTranscription connection:", err)
    os.Exit(1)
}

// call connect!
wsconn := dgClient.Connect()
if wsconn == nil {
    log.Println("Client.Connect failed")
    os.Exit(1)
}

Speech-to-Text from PreRecorded Audio Quickstart

You can find a walkthrough on our documentation site. Transcribing Pre-Recorded Audio can be done using the following sample code:

// context
ctx := context.Background()

//client
c := client.NewRESTWithDefaults()
dg := prerecorded.New(c)

// transcription options
options := &interfaces.PreRecordedTranscriptionOptions{
    Punctuate:  true,
    Diarize:    true,
    Language:   "en-US",
}

// send URL
URL := "https://my-domain.com/files/my-conversation.mp3"
res, err := dg.FromURL(ctx, URL, options)
if err != nil {
    log.Fatalf("FromURL failed. Err: %v\n", err)
    os.Exit(1)
}

Text-to-Speech WebSocket Quickstart

You can find a walkthrough on our documentation site. Transcribing Live Audio can be done using the following sample code:

// set the TTS options
ttsOptions := &interfaces.SpeakOptions{
    Model: "aura-asteria-en",
}

// create the callback
callback := MyCallback{}

// create a new stream using the NewStream function
dgClient, err := speak.NewWebSocketWithDefaults(ctx, ttsOptions, callback)
if err != nil {
    fmt.Println("ERROR creating TTS connection:", err)
    os.Exit(1)
}

// connect the websocket to Deepgram
bConnected := dgClient.Connect()
if !bConnected {
    fmt.Println("Client.Connect failed")
    os.Exit(1)
}

Text-to-Speech REST Quickstart

You can find a walkthrough on our documentation site. Transcribing Live Audio can be done using the following sample code:

// set the Transcription options
options := &interfaces.SpeakOptions{
    Model: "aura-asteria-en",
}

// create a Deepgram client
c := client.NewRESTWithDefaults()
dg := api.New(c)

// send/process file to Deepgram
res, err := dg.ToSave(ctx, "Hello, World!", textToSpeech, options)
if err != nil {
    fmt.Printf("FromStream failed. Err: %v\n", err)
    os.Exit(1)
}

Examples

There are examples for *every- API call in this SDK. You can find all of these examples in the examples folder at the root of this repo.

These examples provide:

Speech-to-Text - Live Audio / WebSocket:

Speech-to-Text - PreRecorded / REST:

Speech-to-Text - Live Audio:

Text-to-Speech - WebSocket

Text-to-Speech - REST

Management API exercise the full CRUD operations for:

To run each example set the DEEPGRAM_API_KEY as an environment variable, then cd into each example folder and execute the example: go run main.go.

Logging

This SDK provides logging as a means to troubleshoot and debug issues encountered. By default, this SDK will enable Information level messages and higher (ie Warning, Error, etc) when you initialize the library as follows:

client.InitWithDefault();

To increase the logging output/verbosity for debug or troubleshooting purposes, you can set the TRACE level but using this code:

// init library
client.Init(client.InitLib{
    LogLevel: client.LogLevelTrace,
})

Testing

TBD

Backwards Compatibility

Older SDK versions will receive Priority 1 (P1) bug support only. Security issues, both in our code and dependencies, are promptly addressed. Significant bugs without clear workarounds are also given priority attention.
