## Description

Text-to-speech voice-over generation from YAML speaker notes using Azure AI Speech neural voices with SSML pronunciation control

# TTS Voice Over Skill

Generates per-slide WAV voice-over files from YAML `speaker_notes` using Azure AI Speech neural voices with SSML pronunciation control.

## Overview

This skill reads `content.yaml` files from a PowerPoint skill content directory, extracts `speaker_notes` fields, applies acronym aliases for correct pronunciation of technical terms, and produces one WAV file per slide. Supports dry-run mode for SSML template verification without Azure credentials.

Synthesis uses Azure AI Speech neural voices, including the HD voices such as `en-US-Andrew:DragonHDLatestNeural`. HD voices are offered in a subset of Azure regions; check the [Speech service regions](https://learn.microsoft.com/azure/ai-services/speech-service/regions) before choosing `SPEECH_REGION`.

Narration produced by this skill is synthetic. Tell listeners that the voice is AI-generated, following Microsoft's [disclosure design guidelines for synthetic voices](https://learn.microsoft.com/azure/foundry/responsible-ai/speech-service/text-to-speech/concepts-disclosure-guidelines). HVE demo-material CI does not synthesize speech; it generates silent videos.
