Speech Data Engineer

The Speech Data Engineer is a key specialist bridging the data market with our technological needs. You will be responsible for identifying unique data sources, evaluating their quality, and building strong relationships with data providers.

Responsibilities

• Collect and prepare speech datasets (ASR/TTS) across multiple languages when customer data is unavailable.

• Process raw audio data, including speech segmentation, speaker separation, and basic preprocessing.

• Run speech recognition and pseudo-labeling, and collaborate with crowdsourcing/labeling platforms to improve data quality.

• Understand and apply differences between ASR data (noisy, real-world speech) and TTS data (clean, high-quality recordings).

• Organize, version, and maintain speech datasets, ensuring teams always know what data exists and where it lives.

• Support existing data infrastructure and pipelines (e.g. DVC).

• Work with external data providers, evaluating dataset quality and contributing to make-vs-buy decisions.

Requirements

• Hands-on experience with speech data processing and labeling tools, such as VAD, Pyannote, whisper, and other segmentation or diarization frameworks.

• Familiarity with quality assessment metrics, including SNR (Signal-to-Noise Ratio) and other acoustic analysis indicators.

• Collect, process, and curate speech datasets, including audio recordings, transcripts, and metadata for multilingual ASR and TTS applications.

• Work closely with internal ASR/TTS development teams to align dataset specifications with model training needs.

• Label and validate audio data, ensuring transcription accuracy, speaker diversity, and consistent metadata standards.
