Ntcham Speech-to-Text: Preserving a Language Through AI

Introduction

Ntcham (also known as Bassari) is a Niger-Congo language of the Gur branch, spoken primarily in the central and northern regions of Togo and across the border in Ghana. With around 200,000 speakers, it is an essential part of daily life, oral tradition, and cultural identity for the Ntcham and Bassari peoples. However, like many minority languages, Ntcham faces challenges in the digital age: few resources exist for automatic transcription, subtitling, or text-to-speech. Speechyou changes that by offering a dedicated Ntcham speech-to-text service that transcribes audio and video into text and generates SRT and VTT subtitles.

Why Accurate Transcription for Ntcham Matters

Accurate transcription is not just a convenience; it is a tool for language preservation. Ntcham is primarily oral, and many speakers are older. Without written records, valuable knowledge — from folk tales to agricultural techniques — risks being lost. By converting spoken Ntcham into text, Speechyou helps create a written archive that can be studied, taught, and shared. Moreover, subtitled videos allow hearing-impaired community members to access content, and they help non-speakers learn the language.

Challenges in Transcribing Ntcham

Ntcham presents several specific challenges for automatic speech recognition:

• Tonal system: Ntcham uses three phonemic tones (high, mid, low). Many words differ only by tone, e.g., báká (to laugh) vs. bàká (to cut). Standard ASR models often miss these distinctions.
• Limited digital data: Ntcham has very few transcribed audio datasets, making it hard to train conventional models. Speechyou uses transfer learning and custom data collection to overcome this.
• Dialectal variation: The three main dialects — Bassari, Eastern Ntcham, and Western Ntcham — have distinct phonetic and lexical features. A one-size-fits-all model would fail. Speechyou's system is dialect-aware.

Use Cases for Ntcham Transcription

Oral History and Cultural Preservation

Community leaders record interviews with elders. Speechyou transcribes these recordings, producing searchable texts that can be archived in local libraries or online platforms.

Educational Content

Teachers in Ntcham-speaking areas can create subtitled videos for their lessons. This supports literacy in Ntcham and helps students who are not fluent in the national language (French or English).

Religious and Community Media

Churches and radio stations often broadcast in Ntcham. Subtitles make these broadcasts accessible to deaf community members. Transcripts also allow for easy translation into other languages.

Podcasts and Video Content

Content creators who speak Ntcham can reach a broader audience by adding subtitles. Speechyou generates SRT and VTT files that work with YouTube, Vimeo, and other platforms.

Linguistic Research

Linguists studying Ntcham can transcribe field recordings quickly, speeding up analysis of grammar, phonology, and discourse patterns.

How Speechyou Helps

Speechyou's AI is built to handle low-resource languages. For Ntcham, we have:

• Custom acoustic models trained on Ntcham speech from multiple dialects.
• Tone-aware transcription that outputs correct diacritics.
• Easy export to SRT and VTT subtitle formats.
• Continuous improvement as more users provide audio, the model learns and gets better.

Getting Started

To transcribe Ntcham audio, simply upload your file (MP3, WAV, MP4, etc.) to Speechyou and select "Ntcham" as the language. Within minutes, you'll receive a transcript and subtitle files. It works on clear recordings, but even with some background noise, the AI performs well.

Conclusion

Ntcham is a living language with a rich oral tradition. Speechyou empowers speakers, educators, and researchers to preserve and share it through accurate speech-to-text and subtitling. By supporting minority languages like Ntcham, we help ensure they thrive in the digital world.
