Transcription Services in Action: Case Studies
Transcription for AI
High-quality transcription is the foundation of reliable AI. From speech recognition to video captioning and document digitization, transcription services provide the text data that algorithms need to learn, adapt, and perform at scale.
Automated transcription tools can help, but human expertise remains essential – to ensure accuracy in noisy environments, capture low-resource languages, and remove bias that machines alone can’t detect. That’s why companies expanding into new markets rely on native speakers and domain experts to deliver transcriptions that reflect real-world usage.
With LXT, you get transcription that is not only fast and scalable, but also inclusive, accurate, and tailored to your AI use case.
