You are building content for a video training solution.

To build narration for video training content using Custom Neural Voice, we must know where each step is done:

Creating a Custom Neural Voice

A Custom Neural Voice is a text-to-speech (TTS) feature within Azure AI Speech.

It allows you to create a unique, natural-sounding synthetic voice.

The correct tool to build and configure a custom voice is the Speech Studio portal.

Not the Language Understanding portal (LUIS), Azure portal directly, or Bot Framework Composer.

Generating narration

Narration requires converting written text into speech.

This is done via the Text-to-Speech service in Azure AI Speech.

Other options:

Language Understanding → For intent/utterance processing, not narration.

Speaker Recognition → For identifying/authenticating speakers, not narration.

Speech-to-text → Converts spoken words to text (the opposite direction).

Thus:

Custom Neural Voice → Speech Studio portal

Narration → Text-to-speech

Correct Answers:

Custom neural voice: The Speech Studio portal

Narration: Text-to-speech
