Voice artificial intelligence (AI) technology becomes increasingly common in everyday life, for example, automated phone services, voice assistive systems (e.g., Siri), and social chat bots. However, most research has focused on how younger adults perceive modern AI speech, leaving the development of this age-uninformed. Recent work indicates that older are less able to identify speech compared adults, but underlying causes unclear. The current study with (N=133; 22-39 years) (N=146; 54-79 investigated potential factors could explain age-related reduction identification. In Experiment 1, we whether high-frequency information – which have access due hearing loss contributes age-group differences, our results showed were both full-bandwidth above 4 kHz was removed.

Two online experiments were conducted with real stretching across unprocessed, processed, ultra-processed continuum. Study 1 was assess accuracy which people could identify while 2 explored how disclosure an image's origin influenced depicted food. The participants in found it very easy recognize particularly case foods. Notably, without disclosure, often preferred. At same time, however, that a image genuine significantly boosted its appeal, whereas revelation had been generated by AI mitigated effect.

Neural activity in auditory cortex tracks the amplitude-onset envelope of continuous speech, but recent work counterintuitively suggests that neural tracking increases when speech is masked by background noise, despite reduced intelligibility. Noise-related amplification could indicate stochastic resonance – response facilitation through noise supports tracking, a comprehensive account lacking. In five human electroencephalography experiments, current study demonstrates generalized enhancement due to minimal noise. Results show (1) enhanced for at very high signal-to-noise ratios (~30 dB SNR) where highly intelligible; (2) this independent attention; (3) it generalizes across different stationary maskers, strongest 12-talker babble; and (4) present headphone free-field listening, suggesting neural-tracking real-life listening. The paints clear picture enhances representation onset-envelope, contributes tracking. further highlights non-linearities induced make its use as biological marker processing challenging.

Fluctuations in masker intensity can reveal glimpses of speech support intelligibility, but older adults have frequently been shown to benefit less from than younger when listening sentences.

Assessment of speech intelligibility in noise is critical for measuring the impact age-related hearing loss. However, quantifying often requires a human to manually process responses provided by participant or patient obtain speech-intelligibility score – typically proportion correctly heard words. This manual can be time-consuming and thus costly. The current study investigates whether state-of-the-art Natural Language Processing (NLP) models from Google OpenAI could used calculate scores as an alternative scoring. It was specifically tested NLP capture common speech-in-noise perception phenomena younger older adults (N = 144) listening masked modulated unmodulated babble noise. results show that closely matched scorer (r ∼0.95). main difference is, on average, ∼2% underestimation relative moderate high signal-to-noise ratios. participants making minor errors related misspellings, gender, tense, which are sensitive, but scorers correct prior Critically, known reduction benefit masker.
