Ipili Speech to Text: Preserving a Language Through AI

Ipili is a language spoken by around 40,000 people in the Enga Province of Papua New Guinea. It belongs to the Engan branch of the Trans-New Guinea family and is known for its rich oral tradition. Despite its relatively small speaker population, Ipili is vital for the identity and daily life of the Ipili people. However, like many indigenous languages, it faces challenges from globalisation and the dominance of Tok Pisin and English.

Accurate speech-to-text for Ipili matters because it enables the documentation of oral histories, the creation of educational materials, and the inclusion of Ipili speakers in digital spaces. Without transcription tools, much of this valuable content remains inaccessible to those who cannot read English or Tok Pisin. Speechyou's AI transcription service steps in to fill this gap, providing a way to convert Ipili audio and video into text quickly and affordably.

Challenges in Transcribing Ipili

Ipili presents several unique challenges for automatic speech recognition:

• Prenasalised stops: Sounds like /mb/ and /nd/ are common in Ipili but rare in many languages, requiring specialised acoustic modelling.
• Pitch accent: Meaning can change based on pitch, so a simple non-tonal ASR system would misinterpret words.
• Low resource: There are few public datasets for Ipili, so Speechyou uses transfer learning from related Engan languages and active learning with community-contributed recordings.
• Dialectal variation: The Lolo and Yawan dialects differ from Ipili Proper, necessitating flexible model adaptation.

Speechyou's technology addresses these challenges head-on. The model is trained on a diverse corpus that includes multiple dialects and speaking styles, and it can be fine-tuned with user-provided data. This ensures that transcripts are accurate even for less common variants.

Use Cases for Ipili Transcription

• Oral history preservation: Record and transcribe stories from elders to create a permanent written archive.
• Education: Generate reading materials from spoken lessons for literacy programmes.
• Media subtitling: Add Ipili subtitles to videos for community news and cultural events.
• Research: Transcribe linguistic fieldwork interviews for analysis.
• Accessibility: Provide text alternatives for audio content to assist deaf or hard-of-hearing community members.
• Church and community: Convert sermons and meetings into text for distribution and record-keeping.
