voice-ai-voices_skill

Overview

This skill provides high-quality text-to-speech synthesis using the Voice.ai API, offering 9 curated voice personas, 11 languages, and real-time streaming. It includes a Node.js CLI and SDK for quick integration, with configurable voice design parameters like temperature and top_p for expressive control.

How this skill works

The SDK calls the Voice.ai production endpoint over HTTPS using an API key provided via VOICE_AI_API_KEY. You can generate files, stream audio chunks for long texts, or pipe output directly to disk. Voices and language options are defined in a local voices.json and selectable by voice_id and language code.

When to use it

• Create narrated content (tutorials, documentaries, audiobooks) with tailored personas.
• Produce real-time or progressive audio for long-form text using streaming mode.
• Localize spoken content across 11 supported languages with the multilingual model.
• Prototype character voices for games or animation using the curated personas.
• Generate on-demand speech for apps, chatbots, or accessibility features.

Best practices

• Set VOICE_AI_API_KEY as an environment variable to avoid embedding secrets in code.
• Use streaming for long texts to reduce latency and cost; cache outputs when reusing audio.
• Pick audio format appropriate to use case (mp3 for general use, wav for highest fidelity).
• Tune temperature and top_p: lower for consistent narration, higher for expressive or varied delivery.
• Monitor API usage and handle rate-limit and payment errors per SDK responses.

Example use cases

• Generate a daily narrated news brief in a clear male or female persona and save as MP3.
• Stream long-form stories to a player so listeners receive audio as it’s generated.
• Localize UI voice prompts into Spanish or French using the multilingual model.
• Produce character lines for a game with distinct personas like 'commander' or 'sakura'.
• Create high-quality voiceovers for tutorials and demo videos with adjustable expressiveness.
