Solutions / Audio & speech
Speech and audio data, recorded to your spec.
Conversational and scripted speech, wake words, command sets, and ambient audio — collected from real speakers in the languages, accents, and acoustic conditions your model actually meets.
Definition
Audio data collection
Audio data collection is the process of recording human speech and other sounds from real contributors — under agreed conditions and with signed consent — so an AI system can be trained or evaluated on how people actually sound.
What we collect
The formats teams ask us for.
Not an exhaustive menu — if what you need is not here, it is a custom collection, which we also do.
Conversational speechNatural two-party and multi-party dialogue for ASR and diarization, not read sentences pretending to be conversation.
Scripted & prompted speechRead prompts, command sets, and wake words with controlled coverage of phonemes, digits, and named entities.
Multilingual & accented speechNative and second-language speakers across the languages and regional accents you need to serve.
Emotional & expressive speechThe same content across emotional registers for empathetic and expressive voice systems.
In-domain & call-center audioIVR-style prompts and domain vocabulary (medical, financial, technical) captured in realistic channels.
Ambient & event audioNon-speech sound events and background conditions for robustness and audio classification.
What shapes the spec
The decisions we settle before collecting.
- Languages & locales
- 500+ languages and locales
- Speaker sourcing
- Screened for language, accent, age band, and gender balance against your spec
- Recording conditions
- Studio, quiet room, or in-the-wild channels (phone, far-field, in-car) as specified
- Delivery
- WAV/FLAC audio with per-file metadata, speaker IDs, and verbatim or timestamped transcripts
- Consent basis
- Written commercial release per speaker, before recording
Where it is used
What teams train with it.
- Automatic speech recognition (ASR) in new languages and accents
- Voice assistants and wake-word detection
- Speaker diarization and voice biometrics evaluation
- Text-to-speech (TTS) voice building with consented talent
- Robustness testing against noise, channels, and far-field capture
How we run it
The standards behind every batch.
These apply to every modality — they are the reason the data is usable rather than merely large.
- Collected to a written spec
- Nothing is gathered speculatively. We agree the target — languages, demographics, devices, environments, edge cases — before a single contributor is briefed.
- Contributors paid hourly
- People are paid for their time, including setup and retakes, not a bounty per item. A per-item rate optimises for volume and quietly wrecks quality.
- Documented, informed consent
- Every contributor signs a release granting the usage rights you need before collection begins. You receive the consent artefacts with the batch.
- Discard rather than downgrade
- If an item cannot meet the spec or a bystander cannot be de-identified, it is dropped — not shipped at a discount to pad the count.
- Multi-layer QA with a visible reject log
- Automated checks plus human review, and you see the reject reasons, not just the accepted items.
- Buyer-owned commercial license
- You receive a perpetual, buyer-owned license with a data card recording jurisdictions of capture and the consent basis.
FAQ
Audio & speech collection, answered.
- What kinds of speech data can you collect?
- Conversational dialogue, scripted prompts, wake words and command sets, emotional and expressive speech, domain-specific vocabulary, and ambient or event audio. We collect from screened native and second-language speakers in the languages and accents you specify, in the acoustic conditions your product actually runs in.
- Can you collect speech in low-resource or under-served languages?
- Yes. Because sourcing runs through a vetted global crowd across 150+ countries and 500+ languages, we can reach speakers of languages that off-the-shelf datasets ignore. Thin languages take longer to staff, and we tell you the realistic timeline up front rather than promising coverage we cannot yet reach.
- How do you handle consent for voice data?
- Every speaker signs a written release granting the commercial usage rights you need before recording begins, and is paid for their time. You receive the consent artefacts with the delivered batch, and any recording capturing an unconsented bystander is discarded rather than shipped.
- Do you deliver transcripts with the audio?
- Yes, when you need them. Audio can ship with verbatim or timestamped transcripts, speaker IDs, and per-file metadata, in the schema your training loader expects.
