What makes Sinhala hard to transcribe

Sinhala uses its own rounded abugida, unrelated to the scripts neighbouring languages share — Tamil, Hindi and Sinhala all look different from each other despite regional proximity. The bigger practical issue is data scarcity: Sinhala has far less training audio behind it than Hindi or Arabic, so accuracy leans more heavily on clear recordings than it does for higher-resource languages. Spoken Sinhala also differs from the literary written register enough that a transcript of natural conversation reads differently from a prepared speech.

What your Sinhala transcript looks like

Transcripts come back in the rounded Sinhala script rather than a romanised approximation, so names and everyday words are written the way a Sinhala reader actually expects them, not phonetically guessed.

[00:00 → 00:04] සියලුම දෙනාට ආයුබෝවන්, අද අපගේ රැස්වීම ආරම්භ කරමු.

[00:04 → 00:08] මුලින්ම, පසුගිය මාසයේ ප්‍රතිඵල ගැන කතා කරමු.

How accurate to expect

Clear, formal-register recordings (news, prepared remarks, dharma talks) transcribe most reliably. Fast casual conversation and heavy background noise cost more accuracy than they do for higher-resource languages, since Sinhala has less training audio behind it than Hindi or Arabic.

What usually needs fixing

1. 1 Proper nouns in the rounded Sinhala script, where visually similar loop-shaped letters are more easily confused than in scripts with more angular strokes.
2. 2 Colloquial spoken forms rendered closer to the formal literary register than the speaker actually used.
3. 3 Borrowed English technical and business terms transliterated inconsistently rather than kept in Latin script.

Getting better results

• → Studio or headset audio narrows the accuracy gap with higher-resource languages significantly — background noise costs Sinhala more than it costs English.
• → Formal registers (news, dharma talks, prepared remarks) transcribe more reliably than fast casual conversation, since more of the training data reflects that register.
