Ingrian Speech to Text: Preserving a Critically Endangered Finnic Language with AI

Ingrian (Izhorian) is a Finnic language spoken by a small community along the Gulf of Finland in Russia. With fewer than 100 native speakers, it is considered critically endangered by UNESCO. The language belongs to the northern Finnic branch, closely related to Finnish and Karelian, but has developed unique features due to centuries of contact with Russian and Votic. Ingrian is traditionally unwritten, but a Cyrillic orthography was briefly used in the 1930s for educational materials. Today, the language survives primarily through oral tradition, making automatic speech recognition (ASR) a crucial tool for documentation and revitalization.

Why Accurate Ingrian Speech-to-Text Matters

Preserving Ingrian is not just about saving words; it is about capturing the unique worldview, folklore, and identity of its speakers. Ingrian oral poetry, known as "runos," contains intricate alliteration and meter that are lost if not accurately transcribed. Researchers studying vowel harmony and consonant gradation need precise phonetic data. Furthermore, descendants of Ingrian diaspora communities (e.g., in Finland and Estonia) seek to reconnect with their heritage through language. Speechyou's Ingrian speech-to-text solution enables these goals by converting spoken Ingrian into searchable, shareable text in the native Cyrillic script.

Specific Transcription Challenges

• Phonological Complexity: Ingrian has eight vowel qualities and a system of vowel harmony unknown to most ASR engines. Consonant gradation further complicates recognition — for example, the word "koti" (home) changes to "kodi" in certain grammatical cases. Speechyou's acoustic model is fine-tuned to detect these alternations.
• Data Scarcity: Large-scale ASR requires thousands of hours of audio, but Ingrian has only a few hours of recorded speech, mostly from the 1960s and 1970s. Speechyou uses data augmentation and transfer learning from Finnish to overcome this limitation.
• Dialectal Variation: The three main dialects — Soikkola, Lower Luga, and Upper Luga — differ in pronunciation and vocabulary. Speechyou's model includes dialect-specific sub-models that can be selected by the user, ensuring higher accuracy for each variety.

Use Cases: From Oral History to Subtitles

• Transcribing Oral Histories: Linguists can upload interviews with Ingrian elders and receive accurate Cyrillic transcriptions, which can be annotated for morphological analysis.
• Generating Subtitles for Cultural Videos: Community groups can create subtitled videos of Ingrian songs and rituals, making them accessible to a wider audience on platforms like YouTube.
• Accessibility for the Hearing Impaired: Elderly Ingrian speakers with hearing loss can follow spoken content via real-time transcription.
• Language Learning Materials: Teachers can produce transcriptions of natural speech for classroom use, helping learners map sounds to the Cyrillic script.
• Podcast Production: A podcast in Ingrian can reach the diaspora with automatic captions, preserving the language in a modern medium.
