Gilaki (Arabic script) Speech to Text: A Complete Guide
Gilaki Speech to Text: Preserving a Caspian Language Through AI
Gilaki is a Northwestern Iranian language spoken primarily in Gilan Province, Iran, along the southwestern coast of the Caspian Sea. With an estimated 3.5 million speakers, it belongs to the Iranian branch of the Indo-European family. Despite its rich cultural heritage, Gilaki is considered vulnerable by UNESCO due to the dominance of Persian in education and media. Accurate speech-to-text technology can play a crucial role in revitalizing the language by making digital tools accessible to Gilaki speakers.
Why Accurate Transcription Matters for Gilaki
Most automatic speech recognition (ASR) systems today support only major languages, leaving minority languages like Gilaki underserved. Without dedicated support, Gilaki speakers have to rely on Persian transcription, which loses the unique sounds and words of their mother tongue. This is especially problematic for:
- Oral history preservation: Elders record stories and songs that are passed down orally. Transcribing these in Gilaki ensures they are not lost.
- Local media: Radio stations and TV programs in Gilaki can be subtitled for accessibility.
- Education: Teaching materials in Gilaki can be created from spoken content.
- Accessibility: Deaf or hard-of-hearing speakers can access Gilaki audio through text.
Challenges in Transcribing Gilaki
Gilaki presents several challenges for ASR:
1. Limited Training Data
There are very few publicly available transcribed Gilaki speech corpora. Most ASR models rely on large datasets, which are missing for Gilaki. Speechyou overcomes this by using transfer learning from related Iranian languages and augmenting with small, high-quality Gilaki datasets.
2. Dialectal Variation
Gilaki varies significantly from east to west. For example, the Rashti dialect uses a different intonation pattern than the Lahijani dialect. Words like 'big' (gol in Rashti, goll in Lahijani) differ. Speechyou's model is trained on multiple dialects and allows users to choose their preferred dialect for better accuracy.
3. Complex Script
The Gilaki alphabet includes letters not found in standard Persian, such as ۊ and ۋ. Moreover, the script is written right-to-left, and vowel diacritics (zabar, zir, pesh) are often omitted in informal writing but needed for correct pronunciation. Speechyou outputs text with proper orthography, including optional diacritics when selected.
How Speechyou Helps
Speechyou's Gilaki speech-to-text engine is designed from the ground up to handle the language's unique characteristics. Key features include:
- Dialect-aware transcription: Choose between Rashti, Lahijani, or Langarudi modes, or let the auto mode detect the dialect.
- Native script support: Output in the full Gilaki Arabic script, with correct use of extra letters.
- Subtitle generation: Create SRT and VTT files for videos, making content accessible.
- Custom vocabulary: Upload domain-specific terms (e.g., local plant names, historical figures) to improve accuracy.
Use Cases in Action
- Gilaki Poetry: A poet recites verses in Lahijani. Speechyou transcribes the audio and generates subtitles for a YouTube video. Viewers can read along in Gilaki, and non-speakers can use the translation feature.
- Research on Gilaki Dialects: A linguist records interviews with elderly speakers in Langarud. Speechyou transcribes the interviews, allowing the researcher to analyze the phonetic features of the dialect.
- Local News: A Rasht-based radio station uses Speechyou to automatically transcribe its daily news bulletins. The transcripts are published on the website for readers who prefer text.
The Future of Gilaki in the Digital Age
By providing accurate speech-to-text and subtitling, Speechyou empowers Gilaki speakers to create and share content in their own language. This not only aids in preservation but also gives the language a place in modern media. As more people use the tool, the quality of the model improves through feedback, creating a virtuous cycle. With Speechyou, Gilaki is no longer an invisible language in the world of AI.
