You ain't lyin.  My grandfather used to have one once upon a time ago, but  yeah,   I would love to get my hands on it to go with my talking tape measure so I can do a lot more work, believe that.

There's a few around at varying prices, even a few DIY solutions from hackerspaces. The cheapest ones i've found so far are one on blind bargains [here] for 39.95$, and another chinese model that speaks english [here] for 27.95$.

There are a couple others though, like one from AbleData [here] price unknown, another called VM10 from Micro Seven [here] also price unknown, and one from Special Needs Computers [here] for 1644.00$.

Hey, why not build one with a Raspberry Pi? I tried it myself, and got pretty far. Unfortunately, I was missing a few parts. But someone posted a quick guide to building it with a Python script, some basic circuit elements, and as the speech output, you could redirect output to a software synth like eSpeak. Once you have that working, slap on a good-fitting case, hook things up to a bread board for ease of organization, and you got yourself a nice multimeter with voltage reading and such. I'm curious to see if someone can build it using an Arduino though. I haven't gotten comfortable enough with soldering to make concrete designs.

The one on blind bargains is sold out yes, but theres another like it on the source site on the right panel thats still available for the same price [here], 10 function with 9v battery.

The chinese model I found sifting through a forum thread [here], theres an image that states it has "standard english pronounciation", and according to some of the users there it does speak english.

I bought two of them, because I spent years trying to find one, and so I didn't want to take the risk of not being able to find one again.

Those kind of translation issues are common on Chinese products but that doesn't necessarily mean the products aren't good, just that english isn't their first language. China's kind of the worlds manufacturing hub, so a lot of products can be manufactured there much cheaper and in bulk than elsewhere, its one of the reasons companies including Apple like to outsource their manufacturing such as for the iPhone there. Another thing is that because of their, ahem, loose adherence to copyrights and patents you can often get manufacturer's selling off brand goods closer to cost with less markup than traditional outlets, and competition there can be quite fierce. This isn't to say you shouldn't check for quality though, but that could be said for any online marketplace you buy from.

Checking a few chinese oriented outlets like Alibaba and AliExpress i've found quite a few other talking Multimeters from a few sellers, such as this one [here] for 38.30$, another [here] is on sale for 20.23$, and another [here] for 48.93$. Theres no mention of what languages they speak specifically so you should contact them first to make sure, also watch out for shipping costs.

Theres also another one [here] direct from a manufacturer for 10.36$, but the minimum order is 1000 units, says it supports multiple languages but not specifically which ones.

Edit: Hmm, actually that chinese one on sale for 20$ looks exactly like the one from Blind Bargains thats still available...
