pftom c12c816a44 feat(design-systems): add new design systems for Agentic, Airtable, Ant, Apple, Application, Arc, and Artistic
- Introduced comprehensive design documentation and JSON configurations for multiple design systems, including Agentic, Airtable, Ant, Apple, Application, Arc, and Artistic.
- Each design system includes detailed guidelines on visual themes, color palettes, typography, spacing, layout, components, and interaction principles.
- Enhanced the overall design framework to support diverse user interfaces and improve consistency across applications.

This update significantly enriches the design resources available for developers, enabling them to create visually cohesive and user-friendly applications.

Text-to-Speech

Generate speech audio locally using Kokoro-82M (no API key, runs on CPU).

Voice Selection

Match voice to content. Default is af_heart.

Content type Voice Why
Product demo af_heart/af_nova Warm, professional
Tutorial am_adam/bf_emma Neutral, easy to follow
Marketing af_sky/am_michael Energetic or authoritative
Documentation bf_emma/bm_george Clear British English
Casual af_heart/af_sky Approachable, natural

Run npx hyperframes tts --list for all 54 voices (8 languages).

Multilingual Phonemization

Kokoro voice IDs encode language in the first letter: a=American English, b=British English, e=Spanish, f=French, h=Hindi, i=Italian, j=Japanese, p=Brazilian Portuguese, z=Mandarin. The CLI auto-detects the phonemizer locale from that prefix — you don't need to pass --lang when the voice matches the text.

npx hyperframes tts "La reunión empieza a las nueve" --voice ef_dora --output es.wav
npx hyperframes tts "今日はいい天気ですね" --voice jf_alpha --output ja.wav

Use --lang only to override auto-detection (e.g. stylized accents):

npx hyperframes tts "Hello there" --voice af_heart --lang fr-fr --output accented.wav

Valid --lang codes: en-us, en-gb, es, fr-fr, hi, it, pt-br, ja, zh.

Non-English phonemization requires espeak-ng installed system-wide (brew install espeak-ng on macOS, apt-get install espeak-ng on Debian/Ubuntu).

Speed Tuning

  • 0.7-0.8 — Tutorial, complex content
  • 1.0 — Natural pace (default)
  • 1.1-1.2 — Intros, upbeat content
  • 1.5+ — Rarely appropriate

Usage

npx hyperframes tts "Your script here" --voice af_nova --output narration.wav
npx hyperframes tts script.txt --voice bf_emma --output narration.wav

In compositions:

<audio
  id="narration"
  data-start="0"
  data-duration="auto"
  data-track-index="2"
  src="narration.wav"
  data-volume="1"
></audio>

TTS + Captions Workflow

npx hyperframes tts script.txt --voice af_heart --output narration.wav
npx hyperframes transcribe narration.wav  # → transcript.json with word-level timestamps

Requirements

  • Python 3.8+ with kokoro-onnx and soundfile
  • Model downloads on first use (~311 MB + ~27 MB voices, cached in ~/.cache/hyperframes/tts/)
