A voice prosthesis device for use with the surgical implant ..
For example, it's well known that the most frequent word in SPOKEN English is "I", and it wouldn't surprise me if that has risen considerably in the written corpus, since the web is often very self-oriented.
What is the passive voice of when did you meet
The tendency is observable in advertising written in French, German, and Italian, and no doubt in other languages not known to your correspondent, who also doesn't know whether using the informal form to address a public official is still within the definitiion of the crime of "insult" and punishable by a fine, as it was in Germany as recently as 30 or so years ago.
A little quibble with your terms, however: An /s/ by definition is always voiceless; if a sound is created at the same point of articulation as /s/ and voiced, it becomes a /z/.

Step 5. Check that the stoma occlusion isn't interfering with the flow of air or the vibration of the pharyngoesophagus when trying to voice open tract. (you may need to periodically replace the dilator so that you can swallow saliva, and so that the puncture stays fully dilated.) If using finger occlusion, do not exert inward pressure which might "pinch" the esophagus. Gently but completely cover the stoma with the finger. As you start to voice, the stoma usually will move forward to meet your finger. Also make sure that your finger doesn't block the prosthesis. If that doesn't solve the problem, go to Step 6.

Step 4. The puncture needs to be fully open to a diameter that is slightly larger in diameter than the prosthesis (eg, 22 French for a 20 French prosthesis) to have an easy insertion. Start with a dilator/stent/catheter that is slightly smaller in diameter than the puncture - it should slide easily in and out of the puncture with a lubricant. Move to successively larger diameter stents/catheters until thedilator that is slightly larger than the diameter of the prosthesis (eg, 22 French for a 20 French prosthesis) slides easily in and out of the puncture tract. That can take hours sometimes, even overnight, but don't rush it. Once it is fully dilated, check that the open tract voicing is good. If it is, the puncture tract length is measured and the correct prosthesis is inserted. If the open tract voice is still not good after you know that the puncture is fully dilated, go to Step 5.

Step 2. If the problem is with the prosthesis (voice is good open tract), the puncture should be dilated a sufficient length of time, and then the puncture tract length is carefully measured (not just a guess!). The prosthesis is inserted. Wait a few minutes if a gel cap insertion is used, so the capsule will completely dissolve. If the prosthesis is the correct length and properly inserted, it should rotate freely in the tract while it is still attached to the insertion tool. And if it is correctly inserted, you should feel resistance to gently trying to pull it back out while still attached to the inserter, because the esophageal flange is fully deployed in the esophagus. In many laryngectomees, you can see the esophageal flange of the prosthesis by passing a flexible endoscope through the nose and down into the upper esophagus. If the prosthesis is seen, you know that you have the correct size and that it is fully inserted into the puncture. It can be hard to see it sometimes because of secretions, the way healing occurs after surgery, and the absence of the usual landmarks that are there before surgery. Some tricks to get a good view: the scope is advanced slightly below the prosthesis. The examiner can tell where the scope is because the light of the scope will shine through the tissue allowing you to see it on the outside of the neck. You should occlude the stoma and try to voice on a long 'ahhhh' or 'eeeee' as the examiner very slowly removes the scope, and usually the prosthesis will be seen for a brief instant. It helps to record the exam and play it back because sometimes you think that you see the prosthesis but aren't sure. If the prosthesis isn't visualized with the scope, it may still be correctly inserted, just not easily visible. If the voice is worse with the prosthesis inserted in the puncture compared to open tract voicing, the prosthesis may be the wrong length or not correctly inserted, or you may need a prosthesis that has a lower resistance to the flow of air. The different types of prostheses have different levels of resistance.
