Speechmatics releases Universal Time Alignment, our language-independent forced-alignment service to match words in text files to their counterparts in audio files, accurately and automatically delivering improved content discoverability, in any language!
The R&D team at Speechmatics have used their deep learning expertise to create a highly accurate and automated system for aligning audio to text.
By synchronising audio to text, Universal Time Alignment can be used for the creation of closed captions and subtitles, indexing archives and enriching human generated transcripts with extra metadata that would usually be carried out laboriously by hand. In an industry where metadata and searchability is becoming increasingly crucial, time alignment offers a simple and very cost effective way of making audio, video and text searchable across any language. To create Universal Time Alignment we extracted elements from our modular speech recognition technology, re-engineered them for the purpose and added additional alignment specific technology based on our machine learning expertise and experience. As a result we have created a system that is not only robust and accurate, but crucially able to cope with any language in the world.
“Any language in the world” was not quite specific enough as Dr Tom Ash (Director of Speech Recognition at Speechmatics) found out – “when we told the commercial team it would work with foreign languages, we were confident that we would cope with the French and German broadcast and telephony they were intending to throw at the system. However, when they discovered that we had successfully time-aligned 14th century Italian epics and the works of Chinese poet Xu Zhimo, even they were surprised.”
Speechmatics’ Universal Time Alignment system is a game changer in an industry that has long suffered from over-promise and under-delivery. This technology is a big step in helping bring the efficiency savings of these technologies to more difficult audio.
There are still many cases where audio quality is too low for traditional ASR to add value or save time in the workflow. However, for the cases where a human transcript has to be created, time alignment can now be used on the human transcript to add further value, reduce the cost of human time stamping and aid discoverability. We encourage everyone to visit our site at www.speechmatics.com/register to see for themselves how we can help content owners and transcribers extract the most value from their audio and video inventory.
