By the end of this article, you will have a better understanding of how Azure AI Speech can help you create realistic and engaging avatars that can communicate with yourself and others in a more natural and human-like way.

What is Azure AI Speech?

Azure AI Speech is a cloud-based service that allows you to create high-quality speech synthesis and recognition for your avatars. It uses state-of-the-art neural networks and deep learning techniques to generate natural and human-like speech from text or audio input. You can also customize the voice, accent, tone, and emotion of your avatar’s speech to suit your needs and preferences.

why is it important for avatar-making?

Creating a realistic and expressive avatar is not an easy task. It requires a lot of time, effort, and technical skills to design, model, animate, and render your avatar. Moreover, adding speech to your avatar can be even more challenging, as you need to record, edit, and synchronize your voice or use a generic text-to-speech engine that may not sound natural or match your avatar’s personality.

This is where Azure AI Speech comes in handy. It simplifies and streamlines the process of adding speech to your avatar, by allowing you to generate high-quality speech synthesis and recognition with just a few clicks. You can also use Azure AI Speech to create multilingual and cross-cultural avatars that can speak in different languages and dialects, without having to learn or record them yourself.

How to use Azure AI Speech

Azure AI Speech is a service that allows you to create high-quality speech-enabled applications with ease. You can use it to transcribe speech to text, synthesize text to speech, translate speech to speech, and identify and verify speakers. You can also customize your speech models and voices to suit your needs and preferences.

Create an Azure account and a Speech Resource

• If you don’t have an Azure account, sign up for one at Azure Portal.

• Once logged in, navigate to the Azure Portal and create a new Speech resource. This resource acts as a container for your speech-related assets and configurations.

• After your Speech resource is deployed, select Go to resource to view and manage keys. You will need the subscription key and region values to authenticate and connect to Azure AI Speech services.

Choose a programming language or tool and a speech service

• Decide whether to use Azure SDKs for your preferred programming language or the REST API directly. SDKs are available for languages like Python, C#, Java, Node.js, etc. The REST API can be used with any language that can make HTTP requests.
• Choose a speech service that fits your application’s requirements. Azure AI Speech offers different services like Speech Recognition, Text to Speech, Speech Translation, and Speaker Recognition.

Install the SDK or use the REST API

• If you choose to use Azure SDKs, install the Azure SDK for your programming language. Include the Azure Speech SDK in your project and use the provided classes and methods to interact with Azure AI Speech.
• If you choose to use the REST API, use the subscription key and the endpoint URL associated with your Speech resource to authenticate and make requests to the Azure AI Speech services.

Use the speech service in your code

• Depending on the speech service you choose, you need to send different types of input and handle different types of output from the Azure AI Speech services.
• For Speech Recognition, send audio files or real-time audio data to the Speech API to convert spoken language into text. You can also specify the language, format, and other parameters of the input and output.
• For Text to Speech, send text input to the API, and it will return an audio file containing the synthesized speech. You can also choose the voice, language, style, and other parameters of the input and output.
• For Speech Translation, send spoken language in one language, and the API will return the translated text or spoken language in another language. You can also choose the source and target languages, the voice, and other parameters of the input and output.
• For Speaker Recognition, send audio samples for enrollment and verification to identify and verify speakers. You can also create and manage speaker profiles, and specify the confidence level and other parameters of the input and output.

Optimize and scale your application

• Fine-tune your application based on performance needs. Azure AI Speech is designed to scale, allowing your application to handle varying workloads.
• Use Azure AI Speech’s customization features to create custom models and voices for your speech services. You can use Speech Studio, a graphical interface to design and test speech applications without extensive coding, to create and manage your custom models and voices.
• Use Azure’s monitoring and analytics tools to track usage, performance, and errors of your speech services. You can use Azure Monitor, Azure Application Insights, and Azure Log Analytics to collect and analyze data from your speech services.

How to create a custom text to speech avatar

1. Get Consent Video: Record a video where the avatar talent agrees to their image and voice being used for the custom text-to-speech avatar model.
2. Prepare Training Data: Ensure the video is of high quality, ideally recorded in a professional studio for a clean background. Quality matters for a good avatar. Consider factors like speaking style, body language, facial expressions, hand gestures, consistent positioning, and lighting to create an engaging avatar.
3. Train the Avatar Model: Once the talent’s consent is verified, Microsoft will manually handle the initial training of the custom text-to-speech model. You’ll receive notification when the training is done.
4. Deploy and Use Your Avatar Model in Your Apps: Once trained, you can integrate and use your custom avatar model in your applications.
