In the days of dial up, everyone was familiar with the cacophony that was emitted from the modem as it was dialing up (if you need a reminder, listen here). I know that those sounds were all representations of what was happening in the modem while a connection was being negotiated. This infographic does a great job of explaining it: enter image description here

My question is: why bother installing a speaker in every single modem and playing the connection negotiation every time? You could argue that it would help in diagnosing a problem, but then why leave the speaker connected and the volume turned up by default? Some modems had a volume knob, but others like this PCI modem didn't. enter image description here

If it was just for diagnosing problems, surely a technician could have plugged in a speaker to a port on the modem and only listened to it when needed. As far as I know, all internet connection software like AOL showed a progress bar or animated status icon of some form to indicate that a connection was being established. Why add the speaker?

You've mentioned that a technician could have plugged a speaker into the modem, but many problems with modems were of a non-technical nature:

  • Phone number was engaged.

  • Wrong number and a person was answering the phone. Best to know about it early rather than continually calling back.

  • Phone number kept ringing indicating a problem at the other end.

  • General network announcements such as number disconnected.

So there were plenty of end-user scenarios where the speaker came in handy. It was normally enabled by default but with the popular Hayes AT command set modems it could be muted with an ATL0 command.

I could always tell whether I'd connected at 14400, 28800, or 56K based on the sound. –  choster Aug 3 at 2:26

From experience: This really was useful.

In addition to the obvious things like busy signals -- or having a human or fax machine pick up, which happened! -- which @PeterJ mentioned, most of us came to recognize the sound of a successful connection as it was negotiated, so the speaker provided a kind of audible "progress bar" on the connection. For that reason, most of us did leave the speaker turned on until the connection had been made -- though it muted itself automatically after that.

This was also useful when someone dialed into your modem line -- you could hear their confused "Hello?" and pick up the phone to answer them.

It may or may not have originated as a hold-over from the days of acoustic couplers -- but there was certainly enough value to justify a few cents for a minimal speaker.
