| Challenge: | Large-scale, voice-based conversational assistants process each utterance through a multi-stage pipeline that includes wakeword detection, automatic speech recognition (ASR), natural language understanding (NLU), entity resolution, and textto-speech. |
| Approach: | They propose a method to identify customer implicitly satisfied with Alexa's responses by leveraging interpretations of model behavior. |
| Outcome: | The proposed approach produces statistically significant improvements in both offline and online tests. |
