Tolitoli Speech to Text: Preserving a Sulawesi Language with AI

Tolitoli is an Austronesian language spoken in the coastal and inland areas of Tolitoli Regency, Central Sulawesi, Indonesia. With around 100,000 native speakers, it is a vital part of the region's cultural heritage. Yet like many minority languages, Tolitoli has limited digital presence. Speechyou's Tolitoli speech-to-text service aims to change that by providing accurate transcription and subtitle generation for this unique language.

Where Tolitoli Is Spoken

Tolitoli is primarily spoken in the districts of Tolitoli, Baolan, and Dondo, as well as in smaller communities along the coast and in the mountains. The language has several dialects, with the Southern variety around the capital being the most widely understood. Many speakers are bilingual in Indonesian, but Tolitoli remains the language of home, traditional ceremonies, and local storytelling.

Why Accurate Speech-to-Text Matters for Tolitoli

• Cultural preservation: Transcribe oral histories, folk tales, and songs to create digital archives.
• Education: Produce written Tolitoli materials for bilingual classrooms.
• Media accessibility: Add subtitles to local videos and radio broadcasts.
• Research: Enable linguists to analyze spoken Tolitoli efficiently.
• Community engagement: Allow deaf or hard-of-hearing members to follow events via captions.

Specific Transcription Challenges

Tolitoli presents several challenges for automatic speech recognition:

1. Limited Training Data

Unlike major languages, Tolitoli has few public datasets. Speechyou uses transfer learning from related Austronesian languages and allows users to contribute recordings to improve accuracy over time.

2. Phonological Features

Tolitoli includes prenasalized consonants such as /mb/, /nd/, and /ngg/, which can be confused with simple nasals by generic ASR. Our model is specifically trained to distinguish these sounds.

3. Vowel Harmony and Reduction

In rapid speech, vowels may harmonize or reduce, making word boundaries fuzzy. Speechyou's language model incorporates rules for these patterns to maintain high accuracy.

4. Code-Switching

Speakers frequently mix Indonesian words and phrases. Our multilingual engine handles switching seamlessly, so a sentence like "Dia menganu lisu Tolitoli" (He/she speaks Tolitoli) is transcribed correctly.
