Sophia Analytics is able to read and analyze any type of text, identify quickly and precisely the relationship, associations and trends, allowing data scientists, researchers, business analysts and managers to concentrate on what they do best: giving data a meaning. Sometimes it is necessary to analyze and classify recordings and, in general, audio messages. In such cases Sophia Analytics makes use of the Nuance Transcription Engine (NTE). NTE is an accurate automatic transcription of audio data, capable of transforming prerecorded or live audio streams into usable data. CELI applies its linguistic intelligence to NTE, improving and refining the basic linguistic model through the core competences of computational linguists that recognize and enhance the language of each sector, be it banking, assistance, debt collection, telecommunications. The output transcribed by NTE is then integrated into Sophia Analytics for text analysis.
