This project was generated with Angular CLI.

Run this Angular CLI command to get the local environment setup:

ng g environments

This will create the following files for development and production:

src/environments/environment.development.ts
src/environments/environment.ts

Change these files to include your environment setup accordingly. For the examples below we will use the development file:

// src/environments/environment.development.ts
export const environment = {
  /// your setup
};

This project includes clients to both VertexAI and Gemini APIs.

Get an API key from Google AI Studio, then configure it here.

Note that access is restricted to the US. Use a VPN to overcome this limitation while outside the US.

// src/environments/environment.development.ts
export const environment = {
  API_KEY: "<<YOUR-API-KEY-FROM-GOOGLE-AI-STUDIO>>",
};

This setup requires a Google Cloud account and is more advanced both in security and capabilities. VertexAI has access to more advanced Generative AI features (image, code, voice and more) and foundational models.

To secure the API access, you need to create an account and get the credentials for your application so only you can access it. Here are the steps:

• Sign up for a Google Cloud account and enable billing — this gives you access to Vertex AI.
• Create a new project in the Cloud Console. Make note of the project ID.
• Enable the Vertex AI API for your project.
• Install the gcloud CLI and run gcloud auth print-access-token. Save the printed access token - you’ll use this for authentication.

Once you have the project ID and access token, you are ready to move on to the Angular app. To verify everything is setup correctly you can try these curl commands.

// src/environments/environment.development.ts
export const environment = {
  PROJECT_ID: "<<YOUR-PROJECT-ID>>",
  GCLOUD_AUTH_PRINT_ACCESS_TOKEN: "<<YOUR-GCLOUD-AUTH-PRINT-ACCESS-TOKEN>>", 
};

Make sure that your access token remains private so you do not incur into expenses from unauthorised access.

You can find more details into how to setup the VertexAI access in this article

This project supports the regular and streamed APIs for faster responsiveness.

You can use the newest eleven_multilingual_v2, a single foundational model supporting 28 languages including English, Chinese, Spanish, Hindi, Portuguese, French, German, Japanese, Arabic, Korean, Indonesian, Italian, Dutch, Turkish, Polish, Swedish, Filipino, Malay, Romanian, Ukrainian, Greek, Czech, Danish, Finnish, Bulgarian, Croatian, Slovak, and Tamil; or eleven_monolingual_v1, a low-latency model specifically trained for English speech.

You need to generate your API key (Sign In/Profile).

Using your API key you can either use Speech Synthesis to listen to the voices and open Developer Tools/Network to extract the voice-id from the request or use the API as shown below:

curl -X 'GET' \
'https://api.elevenlabs.io/v1/voices' \
-H 'accept: application/json' \
-H 'xi-api-key: <<API-KEY>>'

Pick a voice from the response

{
  "voices": [
    {
      "voice_id": "21m00Tcm4TlvDq8ikWAM",
      "name": "Rachel",
      "category": "premade",
      "labels": {
        "accent": "american",
        "description": "calm",
        "age": "young",
        "gender": "female",
        "use case": "narration"
      },
      "preview_url": "https://storage.googleapis.com/eleven-public-prod/premade/voices/21m00Tcm4TlvDq8ikWAM/df6788f9-5c96-470d-8312-aab3b3d8f50a.mp3",
      ...
    },
  ]
}

Once you have the API key and voice-id you can fill in the remaining entries in the environment file.

// src/environments/environment.development.ts
export const environment = {
  ELEVEN_LABS_API_KEY: "<<ELEVEN-LABS-API-KEY>>",
  ELEVEN_LABS_VOICE_ID: "<<ELEVEN-LABS-VOICE-ID>>",
};

Run ng serve for a dev server. Navigate to http://localhost:4200/. The application will automatically reload if you change any of the source files.

Run ng generate component component-name to generate a new component. You can also use ng generate directive|pipe|service|class|guard|interface|enum|module.

Run ng build to build the project. The build artifacts will be stored in the dist/ directory.

Run ng test to execute the unit tests via Karma.

Run ng e2e to execute the end-to-end tests via a platform of your choice. To use this command, you need to first add a package that implements end-to-end testing capabilities.
