PR sugarlabs#24 contained an invalid SVG that GitHub cannot render. This provides a valid, properly structured SVG icon that: - Renders correctly in all SVG viewers - Uses Sugar orange color palette - Adds AI speech bubble to distinguish from original Speak - Adds sound waves to represent TTS voice synthesis Closes #2
Adds utils/language_fallback.py with: - resolve_lang_code(): maps ISO codes, names, or Kokoro codes to valid Kokoro lang_codes with graceful English fallback - get_supported_languages(): returns all supported languages - is_non_latin_script(): flags languages needing G2P preprocessing (Hindi, Japanese, Chinese) before passing to KPipeline Prevents silent crashes when unsupported language codes are passed to KPipeline. Adds proper logging when fallback occurs. Relates to GSoC 2026 Speak-AI Multilingual Support proposal.
