What is the future niche for speech?

  • Beyond directed prompt, single-slot:

– User frustration : inefficiency, lack-of coverage, lack of flexibility – Competition : Smart Phones

  • Beyond standard “how may I help you” call-routing:

– NLU limited to classify the entire utterance in a meaning bucket – Fall-back to directed prompt follow-up questions

  • The future “niche” for speech/language: complex problem

solving / deep NLU / multi-modality

– What’s my first meeting with Peter next week? – I want to go to Montréal sometime tomorrow afternoon, I`d like to get there before 6pm. – Did that cheque for Bob Smith go through? – I want to go from <X> to <Y>, and stop at a pharmacy on my way.

What is needed?

  • Use-case = Problem solving

– dynamic call-flow – multi-turn decision logic – data-driven optimizations ⇒Not even SCXML is enough

What is needed?

  • Use-case = Deep NLU

– ASR : SRGC grammars insufficient, need generic “language model” (statistical/rule-based/combinations/other?) – NLU :

  • Let’s not standardize the underlying NLU mechanisms
  • Richer semantic representation, beyond slot-value pairs
  • Example : modifiers / quantifiers. Can we find a common

generic representation?

  • Example : relations / frames
  • Standard ontologies / knowledge-bases

What is needed?

  • Use-case = Multimodality

– Emma : can’t wait for it to be a requirement! – Abstract semantics : independent of modality, work with common concepts and have modality dependent rendering – Abstract functionality : independent of modality : can we define a limited common I/O modality independent set of functionalities and let the rendering be modality specific – Multi-source input :

  • Speech / text / touch / history (conversation, application, user

profile / data) – Multi-source confidence

What is needed?

  • Use-case = Complexity

– Maximize reuse:

  • Standard reusable ontologies / Knowledge bases
  • Standard reusable VXML libraries
  • Standard reusable Grammar libraries,
  • Etc.

What is needed?

  • Use-case = R&D Agility

– need to make it easier to vehiculate vendor-specific information
