What You Need to Know Before You Apply

What is the purpose of this trial?

This trial aims to understand how the brain processes and controls speech in healthy individuals. Researchers seek to learn how people perceive their own speech errors and how they learn new speech sounds. English-speaking adults with normal hearing and speech, and no history of neurological conditions, will participate in a speaking task. Participants will contribute to important research on speech mechanisms over a period ranging from one day to four weeks. As an unphased study, this trial offers participants the chance to contribute to foundational research that could enhance understanding of speech processes.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. However, since the study focuses on speech and brain processing in healthy individuals, it might not require changes to your medication routine.

What prior data suggests that this speaking task is safe for healthy adult speakers?

Research shows that tasks like the Exp 3 Speaking Task are generally well-tolerated. Studies have examined how feeling safe affects individuals during speech tasks, revealing that beliefs and expectations can influence their experience. This suggests that feeling safe can alter one's feelings during the task.

The Speaking Task for Speech study, conducted by the University of Wisconsin, Madison, does not test a new drug or treatment. Instead, it aims to understand how the brain processes speech. No reports have linked negative effects directly to this type of task.

As an observational study, not a treatment trial, it primarily involves performing speech tasks. These tasks are generally safe for healthy adults. Participants are divided into age groups to determine if age affects speech processing. The study does not mention any significant risks or side effects from participating in the speaking tasks. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Researchers are excited about this trial because it explores a new speaking task technique designed to improve speech among healthy adults across different age groups. Unlike traditional speech therapy methods that often focus on individuals with speech disorders, this approach aims to optimize speech performance in people without any speech impairments. By understanding how different age groups perform in structured speaking tasks, the trial could provide insights into maintaining or enhancing speech clarity and efficiency throughout a person's life. This could lead to novel strategies for supporting effective communication as we age.

What evidence suggests that the Exp 3 Speaking Task is effective for understanding speech processing?

Studies have shown that specific speaking activities can enhance language learning. Research on speech exercises, such as the Exp 3 Speaking Task in this trial, indicates that structured activities can improve speech accuracy and fluency. These tasks enable individuals to practice and refine their speaking skills, shedding light on how the brain manages speech. While direct data on the Exp 3 Speaking Task is not yet available, similar methods have successfully helped people learn and correct their speech. This suggests that participating in speaking tasks could aid in understanding and improving speech processing. ^{1 6 7 8 9}

The study evaluated the speaking proficiencies of 33 alaryngeal speakers across three groups: esophageal, electrolarynx, and tracheoesophageal puncture, revealing significant differences in voice quality, intelligibility, and overall effectiveness among the groups.

Judges' expertise influenced their ratings of speaking proficiency, indicating that familiarity with laryngectomee communication methods affects the assessment of their speaking abilities.

Lip-reading combined with synchronized acoustic pulses (LR&Lx condition) significantly improved performance in understanding sentences compared to lip-reading alone (LR:alone condition) among 42 adult subjects with normal hearing.

The study established a logistic regression model to account for practice effects and list difficulty, allowing for more accurate assessment of lip-reading performance across different conditions.

A study involving eight hearing-impaired adults showed that communication therapy can effectively change how individuals use repair strategies when they misinterpret spoken sentences, leading to a more diverse approach in communication.

After therapy, participants reduced their reliance on the 'repeat' strategy and began using other strategies, such as asking for simplification or key words, indicating improved communication skills.

In a study involving 4 speakers with chronic apraxia of speech and aphasia, all participants showed improved accuracy in speech production across different treatment intensities and schedules using sound production treatment (SPT).

No significant differences in treatment outcomes were found between the various SPT applications, suggesting that different intensities and practice schedules can be equally effective for improving speech accuracy.

A new speech comprehension test was developed using short everyday passages and on-the-go questions, aiming to better reflect real-world communication compared to traditional sentence recall tests.

The new test showed similar psychometric properties to the sentence test, but it revealed age and cognitive effects that the sentence test did not, suggesting it may provide more nuanced insights into speech perception, especially for hearing-impaired listeners.

A new speech intelligibility test was developed by adapting a list of sentences based on feedback from 60 experts in linguistics and speech science, ensuring high agreement on criteria for familiarity, meaning, and predictability.

The adaptation process resulted in 99 sentences being modified to improve predictability and the use of proper names, creating a standardized assessment tool for speech perception in Brazilian Portuguese for both normal hearing adults and those with hearing loss.

After 18 months of group rehabilitation, the program successfully enhanced communication skills by focusing on linguistic, social, and cognitive aspects.

Phonetic games and targeted exercises were effective methods for improving speech production, reading, and writing skills in participants.

In a study involving 38 students performing a 45-minute vocal loading task, it was found that faster speaking rates led to increased vocal fatigue and changes in acoustic voice parameters, such as higher sound pressure levels and fundamental frequency.

The results indicated that vocal fatigue worsened over time, particularly during fast speaking tasks, suggesting that speaking rate significantly influences vocal strain and fatigue.

Sound Production Treatment (SPT) was effective in improving the accuracy of speech sounds in 6 participants with acquired apraxia of speech (AOS) and aphasia, regardless of whether the treatment was presented in a blocked or random order.

The random presentation of treatment words (SPT-random) showed potential advantages in maintaining improvements for some participants, suggesting that different practice methods may influence treatment outcomes in AOS.

The study involved four speakers with chronic apraxia of speech and aphasia, who underwent Sound Production Treatment (SPT) using both blocked and random practice schedules, showing improvements in word production accuracy for both methods.

While both practice schedules were effective, one participant showed better long-term retention with the random practice schedule, and generalization of treatment effects to untreated words was modest and varied among participants.
