What We Offer

Data Services Designed Around Your Models & Use Cases

We support AI, research, and product teams that need high-quality language data from diverse regions and dialects. Our processes are tailored to your guidelines, tooling, and integration needs.

Voice & Speech Data Collection

Collection of scripted and spontaneous speech, in controlled or natural environments, from target demographics across African and Asian regions.

  • Speaker recruitment and screening by language & profile
  • Environment-aware recording (quiet, noisy, in-field)
  • Custom prompts, call flows, and scenarios

Transcription & Annotation

Human transcription and annotation for audio, chat logs, and text corpora, aligned with your task definitions and annotation guidelines.

  • Verbatim or cleaned transcription conventions
  • Entity, intent, sentiment, and topic labeling
  • Speaker, channel, and diarization tags as required

Linguistic QA & Model Evaluation

Rigorous human review of model-generated outputs—from MT systems to chatbots and ASR—to measure quality, safety, and user readiness.

  • Custom evaluation rubrics based on your goals
  • Side-by-side and blind human comparisons
  • Qualitative feedback to guide iteration

Dataset Preparation & Localization Support

Cleaning, normalization, and structuring of multilingual datasets so your engineering and research teams can focus on modeling instead of manual prep.

  • Normalization and de-duplication of text and audio
  • Metadata design and documentation
  • Localization-aware dataset design for multi-region rollouts

Data Pipelines Built With Linguists in the Loop

We partner closely with your product, research, and data teams to design pipelines where human linguists are involved at critical stages—ensuring your datasets reflect real language use and cultural nuance.

  • Collaborative design of collection and QA workflows
  • Clear task definitions and annotation guidelines
  • Feedback loops from linguists back to your teams
