IBM Research AI at INTERSPEECH 2019

Share this post:

The 20th Annual Conference of the International Speech Communication Association (INTERSPEECH 2019) took place in Graz, Austria earlier this month. IBM Research AI was proud to support the conference as a silver sponsor and to share our latest research results in 17 papers presented at the conference (listed below).

Many of IBM’s clients need to provide customer care over a wide variety of channels, including e-mail, text chat, and spoken interactions over the telephone. Our clients must provide their customers with a uniformly good experience across these different channels and extract actionable insights from these interactions. To meet these goals, we need to improve the underlying speech technologies: speech-to-text, text-to-speech, and spoken language understanding.

IBM serves a wide range of clients operating in many different industries, each with its own unique terminology and requirements. In order to support a broad set of speech applications, we focus on two goals:

  1. building strong base models that give our clients good “out-of-the-box” performance, and
  2. supplying tools that empower our clients to customize models for their own use cases.

Because we are researchers, we also pursue fundamental, exploratory work that may not go into products or services in the near term.

Our Interspeech 2019 papers reflect our short- and long-term goals, and show the depth and diversity of our speech research. We invite you to read the papers that interest you, and reach out to the authors if you want to learn more.

From HPC Consortium’s success to National Strategic Computing Reserve

Founded in March 2020 just as the pandemic’s wave was starting to wash over the world, the Consortium has brought together 43 members with supercomputing resources. Private and public enterprises, academia, government and technology companies, many of whom are typically rivals. “It is simply unprecedented,” said Dario Gil, Senior Vice President and Director of IBM Research, one of the founding organizations. “The outcomes we’ve achieved, the lessons we’ve learned, and the next steps we have to pursue are all the result of the collective efforts of these Consortium’s community.” The next step? Creating the National Strategic Computing Reserve to help the world be better prepared for future global emergencies.
