Inclusion criteria

* The age is greater than 18 years; the gender is not limited * Performed total laryngectomy; * No voice prosthesis has been installed * Be able to take care of themselves mentally and physically, and have good hand coordination ability * With healthy wall sharing with trachea and esophagus * The patient has a desire to restore articulation function * Can speak Mandarin and have a certain reading ability (equivalent to primary school education) * The subject is fully aware of the benefits and risks of this trial and is willing to participate in and sign the informed consent form

Exclusion criteria

* There is serious respiratory system disease or defect * There is a serious skin disease in the tracheostoma * Obvious intelligence and mental disorder * Tracheostoma is narrow and needs cannula implantation * Patients with limitation of mouth opening and other subjects with dyslalia or language disorders (such as subjects with sequelae of cerebral infarction, etc.) * Patients with severe respiratory disease, cardiopulmonary disease (e.g., severe arrhythmia, persons with slow ventricular rate (ventricular rate \<50 beats/ min), acute phase of myocardial infarction and severe heart failure), disturbances of blood coagulation (coagulation index PT, APTT, INR\> 1.5 times of the normal upper limit), septicemia and other patients not suitable * Patients with severe diseases of liver and renal function (liver function index, alanine aminotransferase (ALT), aspartate aminotransferase (AST)\> 2 times of normal upper limit, renal function index, urine creatinine (Cr), blood urea nitrogen (BUN)\> 2 times of normal upper limit); * Patients with local recurrence of tumor or metastatic tumor * If the patient has received esophageal articulation training, the time of training and using esophagus to speech should be less than 6 months * Women planning to have child, in lactation or pregnancy during the whole clinical study * Participated in other clinical trials within 1 month * Other candidates the investigators think not appropriate

Design outcomes

Primary

MeasureTime frameDescription
Change in pronunciation effect (subjective auditory assessment)Baseline, 3 months, 6 monthsVoice recordings judged by two independent evaluators, scored from 1-7, with lower scores meaning worse speech.

Secondary

MeasureTime frameDescription
Change in sound intensity (minimum / maximum / comfortable);Baseline, 3 months, 6 monthsSound intensity of the minimum / maximum / comfortable loudness (measured 3 times per person) is recorded to calculate the dynamic range (in decibels)
Change in total time required to read a textBaseline, 3 months, 6 monthsStandard Chinese text is read out loud, and the total time is recorded.
Change in Voice Handicap IndexBaseline, 3 months, 6 monthsValidated tool to assess Voice handicap. Statements on participant's voice quality and effect on social life are assessed by a five-point Likert-scale, ranged from 0-4, with high scores indicating more handicap (0 = Never, 4 = Always).
Change in longest articulation time (continuous /a/, count)Baseline, 3 months, 6 monthsThe longest duration time of one continuous / a / is recorded by a stopwatch, count and the average of three times are taken at the same time.
Evaluation of operative performanceBaseline, 3 months, 6 monthsStudy-specific questionnaire on feasibility and satisfaction of clinicians
Incidence of Adverse EventsBaseline, 3 months, 6 monthsAny adverse events (including serious adverse events and device defect rates) will be recorded.
Change in Quality of Life by SF-36Baseline, 3 months, 6 monthsPatient reported, 36-item, Score of calculated, ranging from 0-100, the lower the score the more disability. The higher the score the less disability
