TTS Voice Over Skill

Generates per-slide WAV voice-over files from YAML speaker_notes using Azure Speech SDK with SSML pronunciation control.

Overview

This skill reads content.yaml files from a PowerPoint skill content directory, extracts speaker_notes fields, applies SSML 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.

Prerequisites

• Azure Speech resource — Free tier provides 500K characters per month.
• Authentication — Key-based (SPEECH_KEY) or Microsoft Entra ID (SPEECH_RESOURCE_ID).
• Python 3.11+ with uv for virtual environment management.
• Data handling note — Speaker-notes content is transmitted to the configured SPEECH_REGION for synthesis. Operators must pin an approved region and avoid sending regulated or confidential narration.
