Tampulma Speech to Text: Preserving a Ghanaian Language with AI

Tampulma (also known as Tampole) is a Gur language spoken by an estimated 100,000 people in northern Ghana, primarily in the Northern Region. It is a vital part of the cultural identity of the Tampulma people, used in daily conversation, traditional ceremonies, and local governance. Despite its importance, Tampulma remains a low-resource language in the digital world, with limited online content and few technological tools. Accurate speech-to-text for Tampulma can change that, enabling transcription, subtitling, and accessibility.

Why Accurate Tampulma Transcription Matters

For Tampulma speakers, having access to speech recognition means:

• Preserving oral traditions: Elders' stories, proverbs, and historical accounts can be digitized and searched.
• Improving education: Teachers can transcribe lessons, and students can review written notes.
• Enabling subtitles: Tampulma videos become accessible to deaf viewers and non-speakers.
• Supporting research: Linguists and anthropologists can process field recordings faster.
• Empowering communities: Local radio, government meetings, and healthcare communications can be documented.

Challenges in Transcribing Tampulma

Tampulma presents several hurdles for automatic speech recognition:

• Tonal system: Like many Gur languages, Tampulma uses pitch to distinguish words. For example, the word for 'house' and 'to build' may differ only in tone.
• Limited training data: Few publicly available Tampulma recordings exist, making it hard for generic models to learn.
• Dialectal variation: Northern and Southern dialects have distinct pronunciations and vocabulary.
• Orthographic inconsistencies: While written with Latin script, some sounds lack standardized spelling.

Speechyou's AI has been specifically adapted for Tampulma, using transfer learning from related languages and incorporating tonal features. The system allows custom vocabulary to handle place names and local terms.
