Does it automatically amplify your voice or do you need to hold down a button?

You need to hold a button down in order to record your voice. To play music and play back recording, just press and release.

No, when you press the button is automatically extends and lights up and makes noise.

The amplification can be left on normal. My husband, who uses this phone, is legally blind - he doesn't need the amplification either.

No, it has a microphone on it that you have to speak into or play a recorded message into. I took my button apart so I would not hear the clicking of the button in the recorded message as it is attach to the microphone...

You have to turn it on by the remote. Then you can make choice as to amplifying the voices or the sound effects

There is one button on the mic but it has three different ways to activate it. I tested these on my Motorola Moto X with Spotify playing in the background. 1) Single press: Pauses playback; 2) Double press: Next track; 3) Press and hold: Brings up Voice Control so you wouldn't have to say "Ok, Google Now";

On my device, there is a button I have to push to make it pronounce a word. If you don't want to hear it, just don't push the button. To my knowledge, once you push the button, there is no way to adjust the volume.

It just takes input from the speaker output. It does not amplify only attenuate the speaker volume

No, it doesn't. You have to use the volume control on the device you plug it in to.

No, there is no Hold button. Pressing the call button while on a call will end the current call, and pressing the mute button only mutes your microphone. I suppose this is only a problem if you want your caller to hear some kind of hold music, otherwise muting the mic should work just fine.

No. You don't need to hold the IS button down. You just need to push down once and it will work for 5 minutes and then it will automatically turn off.

You do not have to yell in anyway. You can speak in a normal voice and the mic picks up really well. I have used mine in situations where speaking loudly wasn't an option and it worked like a charm.

When you lift the mic it will make a click that you will hear and anyone close to you in the room. It isn't super loud though you will know when you're on mute. Those on the call won't hear it at all, at least my calls have never noticed when I go on mute.

The buttons are small but half the time I just hit them to change stations or volume. The instructions are not very well written so I had to figure it out. I'm not sure how to answer this question really. If you don't mind just hitting buttons until you get results then yes. Hope this helps

It does NOT require pushing a button. However, the first few seconds of voice are not transmitted. It takes a few seconds for activation to kick in. You can have your parent say something (eg one-two-three-four), to trigger the vac, then speak whatever he/she wants to say.

The awnser button on the mic doubles as a mute button. It also stops/starts music and such.

You have to push the button on the microphone or base to talk but you can listen "hands free".
