High-Fidelity Workforce
Calibrated for Multi-Modal AI.

Outsource your complex language, audio, and annotation requirements to our structured professional pipelines.

Audio Transcription

Converting multi-speaker voice logs, interviews, and focus groups into verbatim text with precise speaker tracking tags.

Transcription Quality Review (QA)

Independent audit layers verifying transcript accuracy, matching formatting guidelines, phonetics, and timestamp sync thresholds.

Original: "I think we should proceed now" Transcribed: "we should proceed now" (Agreement: 88%) QA Corrected: "I think we should proceed now." (100% SLA)

Audio Validation

Classifying environmental audio features, identifying background noises, counting speaker profiles, and verifying acoustic conditions.

Audio Signal Integrity: OK Noise floor rating: -48dB (Excellent)

Data Annotation

General dataset tagging, entity relationships, bounding boxes mapping, natural language OCR data, and structured tokenization audits.

We are Cleen Technologies, an enterprise provider of annotations.
Tag: ORGANIZATION

Speech Recognition Validation

Benchmarking automated speech recognition output files against human verbatim transcripts to determine WER error metrics.

ASR Text: "there is something they want"
Gold Text: "there is something that they want"
Word Error Rate: 12.5% [Audit Required]

Linguistic Review

Morphological, syntactic, and localized checks carried out by native translators to audit translations and localized datasets.

Structure Audit: [EN-US -> DE-DE] Syntax Calibration: Passed
