1. .... but does the same time ratio apply to the spoken word
2. ... I have a feeling this us one of those questions that will go into the annals of 'stupid questions'
1. If by the "spoken word" you mean, what you hear when it's being played then the answer is "no, not necessarily"
A "normal" Audio CD will hold 70/80 or 90 minutes of audio/music (depending on the size of disc being used) the actual size of the file/s (MB) is not taken into consideration and is therefore irrelevant.
This type of disc is burnt as a Audio Disc" that you would play in any standard/normal CD player.
However, a "Data Disc" is the opposite, and it's the total amount of MB's that is counted and not the length of the track/s.
Although a Data disc can be used to store MP3 files, a MP3 player or computer is needed to select and replay the files and not a ordinary CD player.
(All and any file that you see in the likes of My Computer/Explorer and copied directly to a CD or DVD are classed as "Data" files)
IE:
Audio Disc = 20 off 6MB MP3/Wav files of 4 minutes = 80 minutes
Data Disc = 175 off 6MB MP3/Wav files of 4 minutes = 696 MB (approx)
(Data files consist of any type of file including Word, Excel not just MP3/Wav files)
2. No more so than many other question that seem hard to grasp.
