The seven participants in the study had mixed or spastic dysarthria with variation in intelligibility ratings from mild to severe. SSR put the most likely word into the line of text and provided five further probable word choices in word prediction boxes. The set was further reduced by using word prediction algorithms. Coupling ASR with first-letter identification decreased the dictionary set from which an ASR system had to match the acoustic signal. The first letter of the target word was typed and then the whole word spoken.

devised Supplemented Speech Recognition (SSR), combining ASR optimised for dysarthric speech, alphabet supplementation, and word prediction. The results showed that participants experienced a significant decrease in the time taken to complete control tasks, such as switching on the TV, and the results of the training package increased computer recognition rates by an average of 5%, though some participants observed no gain from training. In this way, STARDUST did not require intelligibility of speech for machine recognition and was limited in the number of words it could recognise. A computerised training package was also used to build consistency of utterance of each target word production utilising visual and auditory feedback. Speaker dependent recognition models were trained with the speaker’s own output and each target word could was represented by any phonetic realisation as long as sufficient phonemic contrast was present to distinguish it from any other target word. None of the participants were reported to have ALS. The STARDUST (Speech Recognition for People with Severe Dysarthria) project developed a speech recognition model for people with severe dysarthria to understand a small vocabulary of ten to twelve individual words that were selected for easier access to environmental control devices. As at 2019, Amazon’s Alexa digital assistant provided more than one hundred thousand different activities that can be controlled by ASR technology. Amazon launched Alexa in 2014, claimed to be similar in functionality to Siri, as did Microsoft with the Cortana in the same year. In addition to being able to recognise speech, Siri was claimed to understand the meaning of what was said and take an appropriate action.

Microsoft introduced ASR in the Windows operating system in 2007, and In 2011 Apple’s Siri ‘digital personal assistant’ was integrated into the iPhone smart phone. In 1993, “Speakable items”, was introduced as a built-in speech recognition and voice enabled control tool for Apple computers. Launched in 1990, Dragon Dictate is regarded as the first consumer speech recognition product. ĪSR technology has rapidly developed over the past three decades. It can be also used for environmental control, such as changing the channel on a television or control the lighting and heating. ASR technology has many uses: it can convert spoken words into text to dictate emails, find information online, from restaurant bookings to directions, weather and news, make appointments and send messages, and provide real-time spoken translations, among many other uses.

Īutomatic speech recognition (ASR) technology is the process by which a machine, such as computer or smartphone, receives a speech signal and converts it into a series of words in text form. It contributes to a sense of self, while allowing the listener to derive multiple levels of meaning. Speech is a powerful medium of identity and communicates mood, humour, geographical, social and educational background, health status, gender as well as the content of the message. įor many plwALS, there is nothing that can replace the ease or speed of natural speech, citing the extended time it takes to spell a message with AAC and AAC users often use vocalisations and gesture to try to speed up communication. As speech for communication becomes increasing difficult, plwALS can adapt the way they speak to compensate, for example, for reduced breath control or articulatory reserve. Up to 90% of plwALS have been identified as eventually relying on augmentative and alternative communication (AAC) to support daily communication. Between 80–95% of people living with ALS (plwALS) experience progressive dysarthria and increasing difficulty communicating their daily needs using natural speech, and in time, most will be unable to speak at all. Amyotrophic lateral sclerosis (ALS), also known as motor neurone disease (MND), is a progressive, ultimately fatal disease causing increasing muscular weakness resulting in loss of function of limbs, weakness of muscles of the trunk and neck.
