Abstract

Disclosed is a speech aid system that discreetly suggests the next word or phrase to finish a part of speech for someone who cannot recall the correct word. The system, in essence, "whispers the answer" in a user’s ear, allowing the user to normally continue without anyone knowing of the required assistance.

Mild cognitive impairment (MCI) [12] has been found in 10 to 20 percent of people older than 65 [1]. While less debilitating than full-blown Alzheimer's disease, it is marked by a number of troubling symptoms, including decline in memory function. Seniors with subjective memory complaints are, over many years, 4.5 times more likely to develop mild cognitive impairment or dementia than those who do not have such memory complaints [7].

Lexical access (word retrieval) is one memory function most affected by aging [2] and one of the most noticeable to the person . "Tip of the tongue" (TOT) phenomenon can be particularly dramatic, since the individual knows the word but cannot access it. Research mostly agrees that TOTs occur when the semantic representation corresponding to a word is activated, causing a strong feeling of knowing the word, but activation of phonological information about the word is unavailable or incomplete [3].

Research [5] shows that providing phonological cues can help in TOT phenomenon . Thus, priming people with a phonologically related word instead of producing the word itself can lead to improvements in coming up with the word . TOTs typically occur at least once each week for most younger individuals and two to four times per week for elderly adults [6][10]. In conversation, TOT can be embarrassing, especially with common words.

One special case of TOT is repeatedly forgetting words , a sign of dementia [9]. Examples include trying to remember proper nouns or meaningless symbols (e.g., user names, passwords)

An assistive technology is needed for helping the cognitively impaired overcome repeated forgetting.

The solution is a speech aid system that discreetly suggests the next word or phrase to finish a part of speech for someone who cannot recall the correct word . The system, in essence, "whispers the answer" in a user's ear, allowing the user to normally continue

without anyone knowing of the required assistance.

The hardware setup includes:

• Ear buds (i.e. speakers) connected via Bluetooth* to mobile phone

• Microphone connected via Bluetooth to mobile phone

• Mobile phone with touch screen, computer, and display to receive the signal and

display the list of suggested words (speech recognition is performed locally on the device, then the words are hashed to a code and sent to the cloud server )

• Cloud server that stores the "mementos" (e.g., the hashed text, the time, and the suggestions), performs the similarity computation, and returns the list of suggested words, which are also hashed

The speech aid system:
