Why
  1. Speech Intelligibility is a broad heading, used only when no more specific condition is named.
  2. The study's listed conditions name Speech Disorders.
Confidence
High: the new condition is named in the study's own listed conditions. Of 351 hand-checked studies reclassified this way, 68% were exactly right and 84% in the right disease family; the registry's first term was right for 5% (measured 2026-10-21). How we classify →

Study summary

Purpose of the study is the validation and cultual adaptation of the Turkish translation of the London Speech Evaluation Scale (LSE-T), so that it would be used as an assessment tool for Turkish head and neck cancer patients. There is no validated Turkish version of LSE to measure severity of perceptual speech in head and neck cancer patients.

Read the detailed description

The speech function is a multidirectional process that depends on complex neuro-muscular network. The function can be evaluated using instrumental, such as voice analysis computer programmes, scales, or well structured questionnaires. There are many scales for assessment of perceptual speech but there is no validated for head and neck patients. The study will assess the construct validity and adaptation of the Turkish translation of Speech Specific Perceptual Speech Evaluation as known as London Speech Evaluation Scale. The investigators developed the Turkish translation of this scale (LSE-T), according to the cross-cultural adaptation guidelines. Two translators translated the LSE into Turkish and a native English language speaker reverse-translated it into English. The back translation was sent to the original author for proofreading. The LSE scale consisted of 6 parameters and 4 scores related with perceptual speech in head and neck cancer patients.

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Groups and cohorts

  • Cancer Patients

    In outpatients clinic, the first group consists of 60 head and neck cancer patients who were treated by ours. The participants will given the document consists that "bit, bet, but" words and also a brief part of "Diyet passage" who written by Omer Seyffettin. The speech record of patients who read to document, will evaluated by three judges (otorhinolaryngologist). Three judges will scoring to Turkish translation of London Speech Evaluation Scale (LSE-T), consists of 6 parameters. After the six weeks, the records were scored again as randomisely.

  • Healty Control

The participants will given the document consists that "bit, bet, but" words and also a brief part of "Diyet passage" who written by Omer Seyffettin. The speech record of patients who read to document, will evaluated by three judges (otorhinolaryngologist).

What researchers measure

Primary outcomes

  1. Validation of the Turkish Translation of London Speech Evaluation Scale

    Turkish Translation of London Speech Evaluation Scale consists of 6 parameters and 4 scores. The minimum score is 0 and maximum score is 24. The lower scores mean a better than high scores.

    Time frame: Baseline

  2. Validation of the Turkish Translation of London Speech Evaluation Scale

    Turkish Translation of London Speech Evaluation Scale consists of 6 parameters and 4 scores. The minimum score is 0 and maximum score is 24. The lower scores mean a better than high scores.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jul 29, 2021, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
