Re: I need help in my masters thesis -- please read
Would you like someone to actually just go ahead and WRITE the thesis for you?
Quoting gehan kamel <gehan84@xxxxxxxxx>:
My Name is Gehan Mustafa, I am a masters student and a teacher
assistant in Cairo University (Egypt), Faculty of Computers and
Information, IT Department. My Masters Thesis is a about Cocktail
Party Speech Segregation( CASA and BSS models). If you don?t mind I
have some questions concerning the topic:
1. The TDOA (Time Delay Of Arrival) of each time/ frequency
region : how is it calculated ? What is TDOA, i.e. what does it
represent when calculated for each time/ frequency region?
2. How is the local relative level or SNR calculated a priori
for each time frequency regions?
3. If we use in CASA models the relationship between TDOA and
the local relative level (RL, which is known a priori), this means we
need to have the 2 sources unmixed to calculate the local relative
level. Does this mean that such an algorithm is non-realistic to be
tried out since in real world applications, no one has a priori the
4. In my masters thesis, is it more realistic to work on the
ST-Numbers Database or should I use a database which takes into
account the echoing and reverberation effects, for the sake of being
more realistic and more applicable to real world situations which
normally does contain echo and reverberation.
5. Do you advise me to work with CASA models or with BSS (Blind
Source Separation) models? Which is more realistic for real-world
applications? I think that BSS models are more realistic and more
appropriate for me to use in my masters thesis. Do you agree with me
or do you have another opinion?
I would really appreciate it if you could help me out in the
formerly stated points. Thank you very much.
