Guarani Speech to Text: Preserving and Transcribing Avañe'ẽ with AI

Guarani (Avañe'ẽ) is one of the most widely spoken indigenous languages in the Americas, with over 6 million speakers. As an official language of Paraguay, it is used in government, education, and media. However, despite its importance, accurate speech-to-text for Guarani has been a challenge. Most AI transcription tools do not support Guarani, and those that do often fail to handle its unique phonology. This is where Speechyou comes in, offering a dedicated Guarani speech-to-text model that delivers over 95% accuracy.

Why Guarani Transcription Matters

Preserving Guarani is a cultural priority. Transcribing audio materials helps document oral traditions, support bilingual education, and make content accessible. For example, Paraguayan TV stations produce news in Guarani, and subtitling these broadcasts helps reach Spanish-speaking audiences. Researchers in anthropology and linguistics rely on transcripts to analyze discourse and grammar. Additionally, legal and medical settings in Paraguay often require bilingual documentation. Without accurate transcription, errors can lead to misunderstandings.

The Linguistic Challenges of Guarani ASR

Guarani presents several obstacles for automatic speech recognition:

• Nasal vowels: Six contrastive nasal vowels (ã, ĩ, ũ, ẽ, õ, ỹ) that are easily confused with oral vowels.
• Glottal stop: A phoneme represented by an apostrophe, which must be distinguished from vowel hiatus.
• Vowel harmony: A system where vowels in a word share nasality or orality.
• Code-switching: Many speakers mix Guarani and Spanish (Jopará), requiring the model to handle both languages.

Speechyou's acoustic model is trained on thousands of hours of Guarani speech, including various dialects and age groups, to handle these challenges effectively. The model uses data augmentation to increase robustness, especially for low-resource Guarani.
