Transcription for AI

Transcription is used to help train and validate algorithms depending on the type of solution being built. For example, speech recognition algorithms for voice assistants and customer service chatbots are trained using speech recordings and their corresponding transcriptions, whereas text that is transcribed from videos can be used to improve video captioning as well as search engine results.

While technologies currently exist to automate transcription, human involvement is still critical to ensure high accuracy and inclusivity, reduce bias, and manage complex use cases such as audio with high levels of background noise or audio in low-resource languages. To ensure high accuracy specific to their solutions when expanding into new markets, companies need fast access to large numbers of native speakers in their target languages.
