We’ve previously written about one of our core technologies at Cobalt Speech & Language - automatic speech recognition (ASR). When you speak, the ASR system converts your spoken words into text. Another core technology at Cobalt is text-to-speech (TTS), or speech synthesis, which converts written words into spoken audio.

Who Spoke When?

Many people have used automatic speech recognition systems to transcribe audio to text, but there are a host of other items that it’s useful to identify from a stream of audio. One task in particular is called diarization - who spoke when? Knowing this information can help with a range of downstream applications. For example, in meeting summarization, knowing who said something means you can accurately make notes and allocate action items.

Cobalt at ICASSP

Barcelona, Spain

Last week, many of us at Cobalt "attended" the ICASSP (International Conference on Acoustics, Speech, and Signal Processing) conference "in Barcelona".  The conference is one of the premier conferences for speech recognition and signal processing.  This year the conference had four times more "attendees" than any previous year.

Building Blocks of Voice Technology

With a set of simple building blocks, you’re only limited in what you can build by your imagination. The same is true with technology, if we think about building complex applications from simpler building blocks. 

Voice Technology for Video Conferencing

The past few weeks have seen the business world move en masse to online collaboration tools, in an effort to ensure public safety while trying to maintain growth. As more and more people are limited to working from home, it’s more important that they have efficient ways to keep up-to-date with their colleagues, and to collaborate on their shared work.

Bringing Voice Technology to your Organisation

Talking to Alexa

Talking is a natural way for people to interact with each other. Small children can speak long before they can read, write, or type. People can carry on a conversation even when they’re busy doing other tasks. The introduction of virtual assistants like Amazon’s Alexa, Apple’s Siri and Google’s assistant have brought voice interfaces to the mainstream as a way for people to communicate with devices. These are popular with customers who love the ease with which they can be used.
