Naxi Speech to Text: Preserving a Language Through AI

The Naxi language (Naqxi) is a vital part of the cultural heritage of the Naxi people in Yunnan, China. Spoken by around 300,000 people, it is a Sino-Tibetan language with a rich oral tradition and a unique writing system: the Dongba pictographs, used for religious texts, and a modern Latin orthography used for everyday communication and education. As the language faces pressures from Mandarin dominance, accurate speech-to-text technology can help preserve, teach, and promote Naxi.

Why Accurate Naxi Speech Recognition Matters

For Naxi speakers, creating digital content in their own language is a way to maintain cultural identity. Podcasts, YouTube videos, and social media posts in Naxi can reach the community, but they often lack subtitles or transcripts. This limits accessibility for hearing-impaired individuals and for learners who are not yet fluent. Automated transcription can bridge this gap, but only if the technology understands the language's nuances.

The Challenge of Tones

Naxi is a tonal language with four distinct tones: high, mid, low, and falling. Each tone changes the meaning of a syllable. For example:

• gv (high tone) – dance
• gv (mid tone) – broad
• gv (low tone) – to cross
• gv (falling tone) – to wrap

Generic speech recognition systems fail to capture these distinctions. Speechyou's Naxi model is trained on tone-labeled data, ensuring that the output includes the correct diacritics and punctuation to represent the spoken word faithfully.

Dialectal Diversity

Naxi has several dialects. The largest split is between Western Naxi (Lijiang) and Eastern Naxi (Ninglang). Western Naxi has four tones, while Eastern Naxi has three and includes retroflex consonants. Speechyou offers separate models for each dialect, so users can select the one that matches their audio. This dialect-specific approach increases accuracy and reduces the need for manual corrections.

Use Cases for Naxi Speech-to-Text

• Cultural Preservation: Transcribe interviews with elders, folk tales, and Dongba chants to create searchable text archives.
• Educational Content: Generate subtitles for Naxi language lessons, making them accessible to learners worldwide.
• Media Production: Add Naxi subtitles to local documentaries, tourism videos, and social media clips.
• Accessibility: Provide real-time captions for community events and government meetings.
• Research: Linguistics students can analyze transcribed speech for syntactic and phonetic studies.

How Speechyou Handles Naxi

Speechyou uses a custom acoustic model built on a small but carefully curated Naxi corpus. The system supports:

• Tone diacritics in the output (e.g., gv, gv̱, gv̀, gv̂)
• Dialect selection (Western or Eastern)
• Mixed-language audio (Naxi + Mandarin) with automatic language detection
• Export to SRT and VTT for subtitles

Competitor Comparison

Most major transcription services do not support Naxi at all. Google Speech-to-Text lists over 100 languages but excludes Naxi. Whisper (OpenAI) may attempt to transcribe it but with very low accuracy due to lack of training data. Rev and Sonix only cover major languages. Speechyou is one of the few AI tools that offers dedicated Naxi transcription, making it an essential tool for anyone working with the language.

Conclusion

Naxi is a language with a rich history and a bright digital future. By providing accurate speech-to-text and subtitle generation, Speechyou helps Naxi speakers and learners create content, preserve oral traditions, and share their culture with the world.
