South Korean startup Cochlear.ai raises $2 million Series A to detect the sounds missed by speech recognition
Sit humbly for a few moments and pay attention to the different clangs around you. You might listen appliances beeping, cars honking, a dog barking, someone sneezing. These are all sounds Cochlear.ai, a Seoul-based sound recognition startup, is improving its SaaS platform to identify. The company’s goal is to develop software that can identify almost any kind of voice and be used in a wide range of smart hardware, including phones, speakers and vehicles, co-founder and chief executive Yoonchang Han told TechCrunch.
Cochlear.ai announced it has raised$ 2 million in Series A fund, led by Smilegate Investment, with participation from Shinhan Capital and NAU IB Capital. This wreaks its total fund so far to $2.7 million, including a grain round from Kakao Ventures, the financing forearm of the South Korean internet giant. Cochlear.ai will be implemented by its Series A on hiring in the course of the coming 18 months and to increase the dataset of reverberates used to train its deep learning algorithms.
The company was founded in 2017 by a crew of six music and audio research scientists, including Han, who completed his PhD in music information retrieval at Seoul National University. While working on his doctorate, Han noticed” that everyone was really focusing on speech recognition organizations. There are so many companies for that, but analyzing other kinds of chimes are technically quite different from speech recognition .”
Speech recognition technology generally recognizes one or two enunciates at a time, and assumes that people are engaging in a communication, instead of talking over each other. It also exerts linguistic knowledge in post-processing to increase accuracy. But with music or noise levels, every kind of announces typically overlap.
” We is therefore necessary to take care about all different frequency scopes, and there are not only spokespeople, but genuinely thousands of sounds out there ,” Han said.” So we think this will be the next generation of audio acknowledgment, and that was the motivation for our startup .”
Cochlear.ai’s SaaS, called Cochl.Sense, is available as a vapour API and margin SDK, and can currently detect about 40 different clangs, which are grouped into three categories: emergency spotting( including glass divulging, screaming and alarms ), human interaction( which includes using finger snaps, claps or whistlings to interact with hardware) and human status( to identify sounds like coughing, sneezing or snoring for utilize lawsuits like case monitoring or automated audio captioning ).
Han said the company too plans to add new functionality to Cochl.Sense for use in residences( including smart orators ), vehicles and music analysis. Cochl.sense’s flexibility symbolizes it can potentially fit numerous employ occurrences, including turning a smart-alecky talker into a” ascendancy castle” for home appliances by seeing the rackets they realise, or facilitating hearing impaired parties by sending alerts about noises, like car horns, to wearable devices including smart watches.
The music acceptance landscape
Han notes that over the past three years or so, there has been a shift from focusing on speech recognition technology to other clangs as well.
For example, more major tech companionships, like Amazon, Google and Apple, are adding context-aware sound recognition to their concoctions. For example, both Amazon Alexa Guard and Nest Secure detect the voice of glass divulging, while iOS 14′ s sound recognition enabled it to add brand-new accessibility features.
Han said the launches by major tech corporations is a boon for Cochlear.ai, because it means that the market for sound recognition technology is growing. The startup plans to work with many different industries, but is currently focused on smart consumer machines and automotive because that is where the most interest for its application is derived from. For example, Cochlear.ai is currently working on a project with Daimler AG to include its resonate approval in gondolas( for example, alerts if small children is locked inside ), in addition to collaborations with major electronic , telecommunications and consumer good companies.
Software that can identify sounds like gunshots, glass transgressing and other interferences for emergency sensing has been available for decades, but conventional engineering often resulted in false alarms or expected the use of specific microphones and other hardware, Han said.
Other fellowships dedicated to improving sound recognition technology include Cambridge, England’s Audio Analytica, which focuses on context-based chime intellect, and Netherlands-based Sound Intelligence, which develops software for emergency notify and healthcare systems.
Cochlear.ai plans to differentiate by building software that can be used with a wide array of microphones, including in low-end smartphones or USB microphones, without needing to be fine-tuned, instead “il rely on” deep learning to refine its algorithms and reduce fallaciou positives.
During the early stages of construct a dataset for a specific sound, Cochlear.ai’s unit records countless audio tests by themselves exercising older smartphone frameworks and USB microphones, is to make sure that their software will work even without high-quality microphones.
Other samples are gathered from online roots. Once the sound’s initial see simulation reachings a certain level of accuracy, it is then able to search online by itself for more of the same kind of audio times, exponentially increasing the speed of data training. Cochlear.ai’s Series A will enable it to build datasets of audio samples more quickly, allowing it to add more audios to its software.
” All of our co-founders are investigates in this field, so signal processing and machine learning techniques-we are trying many different algorithms, because every sound has different characteristics ,” said Han.” We have to try many different things to make one single simulate that can identify all different sounds .”
