ex-azure/ex_azure_speech

ExAzureSpeech

The non-official Elixir implementation for Azure Cognitive Services Speech SDK. This project aims to provide all the functionalities described in the official speech sdk for Elixir Projects.

Getting Started

To use the Elixir Speech SDK you first need to add the dependency in your mix.exs file.

def deps do
  [
    {:ex_azure_speech, "~> 0.1.0"}
  ]
end

Optionally, you can add the following configuration to your config.exs file, to globally configure all the SDK basic settings.

config :ex_azure_speech,
  region: "westeurope",
  language: "en-US",
  auth_key: "YOUR_AZURE_SUBSCRIPTION_KEY"

Implemented Modules

Speech-to-Text with Pronunciation Assessment

To configure the speech-to-text module, you need to add the following module to your supervision tree.

children = [
  ExAzureSpeech.SpeechToText.Recognizer
]

Supervisor.start_link(children, strategy: :one_for_one)

Example

File.stream!("test.wav") |> SpeechToText.recognize_once()

{:ok,
  [%ExAzureSpeech.SpeechToText.Responses.SpeechPhrase{
    channel: 0,
    display_text: "My voice is my passport verify me.",
    duration: 27600000,
    id: "ada609c747614c118ac9df6545118646",
    n_best: nil,
    offset: 7300000,
    primary_language: nil,
    recognition_status: "Success",
    speaker_id: nil
  }]}

Text-to-Speech

To configure the text-to-speech module, you need to add the following module to your supervision tree.

children = [
  ExAzureSpeech.TextToSpeech.Synthesizer
]

Supervisor.start_link(children, strategy: :one_for_one)

Example

{:ok, stream} = TextToSpeech.speak_text("Hello. World.", "en-US-AriaNeural", "en-US")

{:ok, #Function<52.48886818/2 in Stream.resource/3>}

stream
|> Stream.into(File.stream!("hello_world.wav"))
|> Stream.run()

Readiness

This library is still in continuous development, so contracts and APIs may change considerably. Please, use it at your own risk.
