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 ^1.18)

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.

PreRecorded Audio Transcription 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.NewWithDefaults()
dg := prerecorded.New(c)

// transcription options
options := 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)
}

Live Audio Transcription 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 a callback for transcription messages
// for example, you can take a look at this example project:
// https://github.com/deepgram/deepgram-go-sdk/blob/main/examples/streaming/microphone/main.go

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

// call connect!
wsconn := dgClient.Connect()
if wsconn == nil {
	log.Println("Client.Connect failed")
	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: PreRecorded Audio:

  • From an Audio File - examples/prerecorded/file
  • From an URL - examples/prerecorded/url
  • From an Audio Stream - examples/prerecorded/stream

• Speech-to-Text: Live Audio:

  • From a Microphone - examples/streaming/microphone
  • From an HTTP Endpoint - examples/streaming/http

• Text-to-Speech

  • Save audio to a Path - examples/speak/save
  • Save audio to a user-defined Writer - examples/speak/file
  • Save audio to a Stream/Buffer - examples/speak/stream

• Management API exercise the full CRUD operations for:

  • Balances - examples/manage/balances
  • Invitations - examples/manage/invitations
  • Keys - examples/manage/keys
  • Members - examples/manage/members
  • Projects - examples/manage/projects
  • Scopes - examples/manage/scopes
  • Usage - examples/manage/usage

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.
