Your responsibilities

  • Our conversational AI visual programming language. Together with the rest of the team you will be responsible for designing the language and its runtime behavior. We need to allow human Dialog Owners to manage the complexity as well as deliver unequivocally the best solution for building machine-to-human dialogs. We are currently using a state-machine approach but at some point AI will be involved in executing dialogs as well as generating language.

  • Mini-ASR development - ASRs are optimized for dictation. In conversations there are many phrases that very often get wrongly transcripted by generic third-party systems. That's why we develop custom mini-ASRs which provide proper transcription for NLP models based on our production data. Challenges: Multi-lang and constant improvement of dataset size vs. accuracy ratio.

  • Simple and advanced NLP models - models including NER, Regexp+deep learning, in general the most important matter in terms of AI is fastest possible generalization. Challenges: Multi- lang and improving generalization by using multiple approaches incl. transfer learning, multi-task learning, and others.

  • End-of-speech - allows to maintain natural feeling of conversation through minimizing time of voicebot reaction. Challenges: Multi-lang, improving confidence through working on neural network and data: audio, text, tabular data

  • Voicemail detection - important for proper qualification of outbound calls. Challenges: Proper classification of new undetected cases constantly showing up in production.

  • Software 2.0 - In order to make conversations more personal we need to master the process of continually improving our systems according to data from production. Challenges: currently there are too many manual steps in our process. There’s a huge potential to use customer’s resources - they want control and Quality Assurance process could integrate data tagging function (yes we know that is risky - we have to control it).
