Why conversational data?
Models trained on read speech consistently underperform on spontaneous audio. Disfluencies, overlap, and natural speech rates aren’t in the training distribution. This dataset closes that gap for English (Singaporean). Read more in our guide to conversational vs. scripted speech data.

FAQ
Frequently asked questions
What does the English (Singaporean) speech dataset include?
2,000 hours of spontaneous two-person conversations from 200 vetted native speakers recorded in Singapore, delivered as dual-channel audio with time-aligned transcripts, speaker metadata (age, gender, region, device), and consent documentation.
What makes Singapore English hard for speech recognition?
Singapore English runs from standard English to colloquial Singlish, with particles like "lah", "leh" and "lor" and words from Hokkien, Malay and Tamil. Its syllable-timed rhythm and frequent code-switching trip up ASR models trained on US or UK speech.

Can I use this English (Singaporean) dataset commercially?
Yes. The dataset is licensed for commercial use, including training ASR, TTS, and other voice-AI models. Every speaker has signed explicit commercial-use consent, and we provide the full consent chain for your legal review.
How much does the English (Singaporean) speech dataset cost?
Pricing is $60 per hour of audio. Volume discounts are available for full-dataset and multi-language purchases. Contact us for a quote.
