Bhili Speech to Text: Preserving a Language Through AI

Bhili is a vibrant Indo-Aryan language spoken by the Bhil people, one of the largest tribal communities in India. With an estimated 3.5 million speakers, Bhili is primarily spoken in the western states of Gujarat, Rajasthan, Madhya Pradesh, and Maharashtra. The language is written in the Devanagari script, though historically it has also been written in the Gujarati script. Despite its rich oral tradition of folk songs, stories, and genealogies, Bhili remains under-resourced in the digital world. Accurate speech-to-text technology can bridge this gap, enabling the preservation and accessibility of this unique language.

Why Accurate Bhili Transcription Matters

For Bhili speakers, access to reliable transcription tools can transform how they create content, share knowledge, and interact with technology. From community radio stations to educational YouTube channels, the ability to convert spoken Bhili into text opens up new possibilities. Subtitles in Bhili make videos accessible to deaf and hard-of-hearing community members, while transcriptions of oral histories help linguists and anthropologists document endangered dialects. Moreover, for the Bhili diaspora, automatic transcription can help them connect with their heritage.

Challenges in Transcribing Bhili

Transcribing Bhili is not a trivial task. The language presents several unique challenges for automatic speech recognition:

• Non-standardized orthography: While Devanagari is the preferred script, spelling conventions vary widely. Some speakers use Hindi-style spellings, while others use Gujarati-influenced forms.
• Retroflex and implosive consonants: Bhili has a set of retroflex stops (e.g., ट, ठ, ड, ढ) and implosive stops (e.g., ब़, ड़) that are acoustically distinct but easily confused with plain consonants by generic ASR.
• Dialectal variation: The three main dialects—Wagdi, Bhilodi, and Dungri Bhili—differ significantly. A word like "water" in Wagdi is "pānī", but in Bhilodi it might be "pāṇī" with a retroflex n.
• Limited training data: Unlike Hindi or English, there is very little publicly available Bhili speech data, making it difficult for traditional ASR systems to learn the language.

How Speechyou Overcomes These Challenges

Speechyou’s Bhili model is built from the ground up to handle these complexities. The acoustic model is trained on a custom dataset that includes recordings from all three major dialects, covering diverse speakers and accents. The language model incorporates a lexicon of Bhili words with their standard Devanagari spellings, as well as common variant forms. For implosive consonants, the model uses a specialized attention mechanism that highlights frequency and duration cues unique to those sounds.

Additionally, Speechyou offers dialect selection in the settings, allowing users to choose between Wagdi, Bhilodi, or Dungri Bhili for the highest accuracy. The system also supports real-time transcription, so you can see the text as you speak. For pre-recorded audio, batch processing is available, and the output can be exported as SRT or VTT subtitle files.

Use Cases for Bhili Transcription

• Oral history preservation: Record interviews with elders and automatically transcribe them. The text can be stored in digital archives and shared with future generations.
• Educational content: Teachers can transcribe Bhili-language lessons or stories, making them searchable and easier to annotate.
• YouTube and social media: Creators can add Bhili subtitles to their videos, increasing engagement and accessibility. With Speechyou’s translation feature, they can also create subtitles in Hindi, English, or other languages.
• Research: Linguists studying the Bhil languages can quickly transcribe field recordings, speeding up analysis and documentation.
• Accessibility: Live captions for Bhili webinars, meetings, or events ensure that everyone can follow along, regardless of hearing ability.
