Every language carries its own rhythms, expressions, and ways of connecting. Building technology that understands people starts with recordings that reflect how they actually speak.
CCC provides multilingual speech data collection services, including speaker recruitment, scripted and unscripted recordings, transcription, annotation, and quality assurance. We work closely with your team to understand the languages, speakers, and recording conditions your project needs.
Our focus is custom collection rather than off-the-shelf datasets. From read speech in controlled environments to spontaneous, two-speaker conversations, we coordinate new recordings around your specifications.
Speech Data Built Around Your Requirements
As a multilingual data services provider, CCC brings together language expertise and coordinated recruitment and production workflows.
We take time to understand your intended use, target locales, speaker profiles, recording hours, and acceptance criteria. This helps us identify practical requirements early and prepare a collection plan that works for both your team and the people contributing their voices.
Projects can cover a single locale or multiple languages and dialects under an agreed delivery plan.
Types of Speech Data We Offer
Speaker Recruitment and Locale Coverage
Good collection depends on finding suitable participants and helping them understand what is expected.
We coordinate recruitment against agreed criteria, which may include:
- Native-language proficiency and dialect
- Country or region of residence
- Length of residence in the target locale
- Age range and demographic distribution
- Recording-device availability
- Maximum contribution per speaker
- Consent and participation requirements
Our collection focus includes Tagalog, Philippine English, Cebuano, Indonesian, Malay, and Japanese. Additional languages, dialects, and regions are assessed according to recruitment feasibility, available linguistic support, volume, and timeline.
We discuss feasibility openly so that the proposed scope and schedule reflect what we can responsibly deliver.
Speech Transcription and Annotation
Commission recordings with or without transcription, depending on your project scope.
- Our language data services can include:
- Orthographic transcription in the native script
- Human transcription and automatic transcript post-editing
- Speaker identification and tagging
- Start and end times, timestamps, and alignment
- Dialect and language labels
- Environment and background-noise labels
- Transcript review and linguistic quality assurance
For free speech and conversational recordings, we agree on how to represent hesitations, repetitions, overlapping speech, and code-switching. Clear conventions help preserve the details your team needs while keeping the dataset consistent.
Audio Formats, Metadata, and Deliverables
We prepare deliverables around your collection specifications and data workflow.
| Component | Specifications agreed during scoping |
|---|---|
| Audio files | WAV or another agreed format; sample rate, bit depth, and channel configuration |
| Recording settings | For example, 8 or 16 kHz, 16-bit PCM, where required |
| Transcription files | CSV, JSON, or a client-defined structure |
| Speaker metadata | Agreed fields such as speaker ID, locale, dialect, age, and gender, subject to consent requirements |
| Annotations | Speaker labels, timestamps, and other agreed fields |
| QA documentation | Review results, acceptance status, and agreed quality reports |
We confirm file naming, metadata, segmentation, and delivery structure before production so that submissions are easier for your team to review and use.
From Collection Brief to Accepted Recordings
Consent, Privacy, Licensing, and Data Use
Behind every recording is a person contributing their voice and time. We believe they should understand what they are participating in and how their recordings may be used.
We work with clients to establish clear participant consent requirements and permitted data use before collection begins. Personal information is handled in accordance with our Privacy Policy, with information security practices aligned with ISO/IEC 27001.
Project agreements define the intended AI training or evaluation use, access arrangements, retention requirements, and licensing terms. Exclusivity and any rights to future licensing are discussed explicitly.
Custom collection does not automatically determine ownership or exclusivity; those terms are agreed for each project.

- Total recording hours and number of speakers
- Recording duration or contribution limit per speaker
- Participant profiles and demographic requirements
- Recording environments, devices, and audio specifications
- Transcription, metadata, and annotation formats
- Consent, licensing, and exclusivity
- Acceptance criteria, weekly throughput, and final deadline
We’ll review the requirements with you and prepare a proposal covering feasibility, scope, rates, and delivery.

FAQs
Throughput depends on the locale, recruitment requirements, recording duration, and review scope. We propose delivery targets after assessing the brief and any pilot results, with room to discuss a phased collection schedule.
Depending on the scope, proposals may use rates per accepted recording hour or per defined asset. Pricing reflects recruitment difficulty, collection type, technical requirements, transcription, annotation, and quality criteria.
If you are still developing the scope, you’re welcome to share an initial brief. We can work through the details together.
For now, no. We focus on custom speech recordings collected specifically for your project. We recruit speakers and coordinate collection around your agreed language, speaker, and recording requirements.
We assess recruitment against your required language, dialect, region, and participant profile. We’ll discuss availability and production capacity with you during feasibility review.
A pilot or sample collection can be arranged. We agree on the locale, speaker configuration, duration, recording environment, transcript fields, and commercial terms in advance so that the sample is useful for your evaluation.
Yes. A project can combine scripted read speech, unscripted responses, and spontaneous conversations, with separate instructions and acceptance criteria for each. We can help you plan the collection mix around your intended use.
Yes. We can transcribe recordings in the language’s standard writing system—for example, Japanese using kanji and kana rather than romaji, or Hindi using Devanagari rather than Latin-letter transliteration. Transcription conventions are agreed before production.
