Question 1

What audio formats and quality levels can you deliver?

Accepted Answer

From telephony-grade 8kHz to studio-grade 24-bit/48kHz, in WAV, FLAC, or MP3. We capture across multiple microphone setups and real-world noise conditions (in-car, outdoor, far-field) and deliver time-aligned transcriptions and speaker/emotion labels alongside the audio.

Question 2

Can you source speech in low-resource languages and dialects?

Accepted Answer

Yes. Our 2M+ contributor network spans 100+ languages including low-resource ones like Kinyarwanda, Sundanese, and Sinhala. For specific dialects or accents we run targeted sourcing campaigns with native speakers.

Question 3

What types of data can you collect and annotate?

Accepted Answer

We handle all four major data types — audio/speech, video, image, and text. This includes voice recordings, conversational dialogue, object recognition images, document OCR, video annotation, text classification, and more. Our operations span 100+ languages worldwide.

Question 4

How do you ensure data quality?

Accepted Answer

We use a multi-layer quality assurance process: automated validation checks, trained reviewer verification, and statistical sampling at every stage. Our overall accuracy rate exceeds 98% across all data types.

Question 5

Is the data ethically sourced?

Accepted Answer

Absolutely. Every dataset is collected with documented written consent. We verify contributor identity, maintain full traceability for every file, never use scraped or reused data, and store everything on enterprise-grade infrastructure with end-to-end encryption. We align with GDPR, ISO 27001, and SOC 2 standards.

Question 6

How fast can you deliver?

Accepted Answer

Delivery timelines depend on project scope, but we're built for speed. We can activate contributors within days, not weeks. Our crowdsourced model with 2M+ contributors means we can scale rapidly for high-volume projects without compromising quality.

Question 7

Can you handle rare or low-resource languages?

Accepted Answer

Yes, this is one of our strengths. We have active contributor networks in 100+ languages, including low-resource languages like Kinyarwanda, Mongolian, Sundanese, and Sinhala. For specialized language requirements, we can set up targeted sourcing campaigns.
