From what I recall, some time later a family owned company in WI, made a deal of some kind with the Teleco's to take this idea of weather forecasting into just about every locale in the US on a commercial basis. They purchased, in just about every telephone exchange, the (weather) WE-6-1212 number, and made it available with some specialized equipment, at a monthly charge, to "voice" these service for any business or whom-ever wanted to have their "name" sponsoring these local dial-up's. I knew of car dealer's in up-state NY and of all sorts of other services sponsoring local systems throughout the Northeast.
Most of these boxes (in later years produced digital derived voices; in earlier were analog with stored "phrases" to speak the words) were locally placed on leased phone lines with the weather (WE-6_1212) number for people to call in to get up-to-date weather info (and of course the "commercials" from the sponsor's!). The boxes were remotely accessed to update the weather forecasts, depending upon what "service" the sponsor paid for, and most boxes had local weather instruments feeding them with data so that local temp, barometric readings, etc., were available to be "spoken" to the caller. The voices used (an option of either a male or a female) were the same voice of the (human) persons' who made most all of the "standardized" voices used by the Telcos - example: "The number you've reached is no longer in service....")
This telecom equipment supplier also makes the switch (#5ESS) mounted voice announcers which "voice" the "standardized" voice (intercept, special feature, etc.) announcements for local telcos.
However, with the advent of the computer, many of these local based systems have been removed (I checked the Syracuse - 315AC - line and it is out of service) as one could surmise that this same info is available on-line with much more data (WeatherBug is one of them) such as video feeds to show what local conditions looks like (which can't be done with a land-line but can be accessed on a cell phone with Internet access!)
