You can't use the
standard f0 analysis. There's no such thing as standard. You need a framework e.g. Autosegmental-meterical Phonology (AM)
supposing you are going to work in the phonological category
But again this is when you are going to do a scientific study for a non-scientific observation you can take guess by looking at the pitch track but it's not scientific.
About prosodic transcription systems:
Actually ToBI is not the only system for transcribing prosody. There numerous systems within different frameworks available: INTSINT (Hirst, 1998), IViE (Grabe, 1998), Tilt (Paul Taylor, 1998), RFC (Paul Taylor, 1994)...
ToBI is one of them
The advantages of ToBI over other systems like INTSINT are as follow:
ToBI is easy to learn
One can easily learn ToBI you don't need special guides. only two letters
L which if you happened to be familiar with AM Phonology you have seen them in other systems (in INTSINT). Some special characters like
* need to be interpreted before using and that's easy supposing you have an understanding of AM phonology.
ToBI is easy to use
You can use ToBI right away, no need for special calcuations, no need for usage of other formulae. It's straight.
ToBI is easy to read
Even if your first time looking at a ToBI transcription you can easily guess what are the transcriptions and you can read them easily.
The disadvantages of the ToBI system:
Well, you can't always say that the easiest method is the best one. We still don't know what parts of prosody do we need so that we can throw away the others. ToBI is a system which neglects tremendous amount of prosodic data and that's not right.
In the end it's up to you to choose whatever works for you. But when talking about prosodic data, you have to be careful.
