Human Audio-to-Text Precision

Sinhala Audio & Video Transcription Services

Transform recorded Sinhala speech, interviews, focus groups, and multimedia into accurate, time-coded text. Native human transcription overcoming Sri Lankan dialect variations and Singlish code-switching.

Domain Overview & Linguistic Strategy

Automated Speech Recognition (ASR) systems like Whisper, Google Speech-to-Text, and AWS Transcribe suffer from extraordinarily high Word Error Rates (WER) on Sinhala audio. Sri Lankan spoken discourse features rapid pace, complex vowel lengthenings, background ambient noise, and widespread code-switching between English and Sinhala (Singlish). Naive automated tools produce broken sentences and miss critical context.

At Sinhalaize, transcription is executed by experienced native listeners who transcribe every utterance with contextual discernment. We capture technical vocabulary, accurately spell proper nouns and place names, and deliver structured, speaker-attributed transcripts tailored for research, corporate compliance, and media production.

Whether you need clean-read transcription (omitting false starts and stuttered fillers) or strict verbatim legal transcripts (preserving pauses, repetitions, and vocalizations), our workflows ensure publication-grade fidelity.

We accept all major formats including MP3, WAV, M4A, MP4, MOV, AAC, FLAC, WMA, and shared cloud links (Google Drive, Dropbox, Zoom, OneDrive).

What is the turnaround time for audio transcription?

Standard delivery for clear 60-minute audio recordings is typically 24 to 48 hours. Expedited same-day delivery is available for urgent requirements.
