Summary

The first neural text-to-speech (TTS) implementation for Myaamia, an Indigenous Algonquian language, has been developed in collaboration with the Myaamia Center at Miami University. This initiative prioritizes data sovereignty and utilizes a dataset of 14,358 utterances, totaling 10.4 hours (with 8.18 hours for training) from seven speakers. Researchers trained and evaluated FastSpeech, Glow-TTS, and VITS models using objective metrics like MCD, F0 RMSE, and duration RMSE, alongside subjective expert evaluations. VITS demonstrated superior performance in spectral and prosodic accuracy, although challenges persist in achieving precise phonetic and prosodic modeling. This work confirms the viability of neural TTS for Myaamia, offering significant implications for language learning and revitalization, and provides a replicable framework for other low-resource Indigenous languages under ethical data governance.

Key takeaway

For Research Scientists or NLP Engineers developing speech synthesis for low-resource Indigenous languages, this work demonstrates that neural TTS is achievable. You should consider VITS as a robust model for spectral and prosodic accuracy, while actively addressing challenges in phonetic precision and prosody modeling. Crucially, adopt the ethical data governance and data sovereignty principles outlined to ensure responsible and community-aligned language technology development.

Key insights

Neural TTS is viable for low-resource Indigenous languages like Myaamia, offering a framework for revitalization while upholding data sovereignty.

Principles

• Uphold data sovereignty in language tech.
• Neural TTS aids language revitalization.
• Frameworks should be replicable.

Method

Train and evaluate FastSpeech, Glow-TTS, and VITS models on a custom Myaamia dataset (14,358 utterances, 8.18 training hours). Assess synthesis quality via objective (MCD, F0 RMSE) and subjective expert evaluations, upholding data sovereignty.

In practice

• Consider VITS for spectral accuracy.
• Prioritize data sovereignty in data handling.
• Adapt framework for other low-resource languages.

Topics

• Neural Text-to-Speech
