Speaking Valve Attachment: A speaking valve can be attached to the tracheostomy tube, which facilitates airflow while allowing the patient to speak. The speaking valve creates resistance, similar to the role of vocal cords, enabling patients to produce sounds. This valve regulates airflow, directing air through the vocal tract and facilitating speech production.
Tracheostoma Formation: During tracheostomy, a stoma or an opening is created in the front of the neck. This stoma replaces the natural route of airflow through the mouth and nose, allowing air to pass directly into the trachea. This modification allows patients to produce vocal sounds by vibrating their vocal cords when they attempt to speak.
Use of Electrolarynx: In some cases, an electrolarynx may be utilized. This device generates an artificial sound when pressed against the neck. The vibrations created by the electrolarynx are amplified and transmitted through the tissues of the neck and face, allowing the patient to produce speech. By using this external device, patients can communicate verbally without relying solely on the tracheostomy tube.
However, it's important to note that speaking with a tracheostomy tube may require practice, as it involves different vocal mechanisms compared to normal speech. Speech therapists and healthcare professionals provide guidance and support to help individuals learn and improve their speaking skills while using a tracheostomy tube.
