Betawi Speech to Text: Preserving a Language with AI

Betawi is the vibrant, creole language of the indigenous people of Jakarta, Indonesia. Often described as a Malay-based creole with heavy influences from Javanese, Sundanese, Chinese, Arabic, and Dutch, Betawi is spoken by around 2.7 million people, primarily in the Greater Jakarta area. Despite its cultural richness, Betawi has no official status and is often marginalized in favor of Indonesian. This makes accurate speech-to-text technology for Betawi both a technical challenge and a cultural necessity.

Why Accurate Betawi Transcription Matters

Transcribing Betawi audio is essential for several reasons. First, it helps preserve the language's oral traditions, including folk tales, pantun, and traditional music, which are at risk of fading as younger generations shift to Indonesian. Second, it enables content creators (YouTube vloggers, podcasters, filmmakers) to reach a broader audience by adding subtitles and transcripts. Third, researchers studying language contact, code-switching, and sociolinguistics can analyze Betawi speech more efficiently. Finally, accessibility for elderly speakers who prefer Betawi is improved when captions are available in their mother tongue.

Challenges in Betawi Speech Recognition

Building an ASR system for Betawi is not trivial. The main challenges include:

• Non-standard spelling: Betawi has no official orthography. Words like 'tidak' (no) can be written as 'kagak', 'kaga', 'ga', or 'kagak' depending on the speaker and context.
• Code-switching: Speakers frequently mix Betawi with Indonesian, often within a single sentence. A model must recognize both languages in real-time.
• Phonological features: Betawi uses glottal stops and reduces final consonants. For example, 'makan' (eat) becomes 'mak' with a glottal stop. These are not present in standard Indonesian.
• Dialectal variation: Urban Betawi (Betawi Kota) differs from suburban (Betawi Pinggir) and rural (Betawi Ora) dialects in vocabulary and intonation.

Most commercial ASR tools, such as Google Speech-to-Text, Rev, and Sonix, do not support Betawi at all. Even OpenAI's Whisper, which covers Indonesian, often misidentifies Betawi as Indonesian, leading to poor accuracy.

How Speechyou Handles Betawi

Speechyou is built from the ground up to handle underrepresented languages. Our Betawi model is trained on a curated dataset of spoken Betawi, including recordings from native speakers across different dialects and age groups. We also incorporate text sources like social media posts, online forums, and transcribed oral histories to capture spelling variations.

The system uses a custom language model that:

• Recognizes common Betawi slang and informal expressions (e.g., 'gue', 'loe', 'nyok', 'anjay').
• Distinguishes Betawi from Indonesian even when code-switching occurs.
• Handles phonetic variations like glottal stops and reduced consonants.
• Supports multiple dialectal forms, so you can transcribe Betawi Kota or Betawi Pinggir with equal accuracy.

Once you upload an audio or video file, Speechyou produces a transcript with timestamps, which you can export as plain text, SRT, or VTT subtitles. The editing interface allows you to correct any errors manually, and the AI learns from your corrections over time.

Use Cases: From Folklore to Film

If you are a Betawi cultural activist, you can record interviews with elders and have them transcribed instantly. A filmmaker can add subtitles to a Betawi short film for international festivals. A linguist can analyze patterns of language change from transcribed conversations. And a podcaster can publish show notes and transcripts to improve SEO and accessibility.
