xbl Posted April 17, 2008 Share Posted April 17, 2008 The Grey Ghost and his grey posts... The Gray Ghost would like to point out that the RTBC thread is thattaway, if you ask the mods nicely, they might move it to the right place. Although, it would be fair to concede that the Gray Ghosts previous post was Grey in every possible sense of the word. 0 Quote Link to comment Share on other sites More sharing options...
renton Posted April 17, 2008 Share Posted April 17, 2008 (edited) Multi-Modal Speech Enhancement: An Overview and possible future directions using a MATLAB based Audio-Visual Toolbox.The Gray Ghost thought his presentation was sorted, but is having last minute doubts. Signal processing and noise elimination? sounds good, never really done more with Matlab than scratch the surface to be honest, my PHd is in Electrostatics and Microfluidics so I do use a lot of Comsol - based on Matlab script - though (it isn't very good).

Aye, basically taking in noisy speech signals and converting them into lovely clean speech with all the background chitchat reduced in volume. Hearing aid research basically. The Gray Ghost is looking into using both the noisy audio, and the visual signal (lip movements), to produce a better quality of output. What are Electrostatics and Microfluidics though? The Gray Ghost has not encountered such things! 0 Quote Link to comment Share on other sites More sharing options...

The Gray Ghost has not encountered such things! I guess then the Matlab work is essentially a project demonstrator then? it sounds like a good idea, will be interested in how you plan to get your code into a hearing aid at low cost, you will need to scale down a fairly complex DSP will you not? Oh come now, Electrostatics as in the E-field component of the electromagnetic field. Static electric fields, sounds simple until you try to conformally map it to periodic domains wihtout using a numerical computational solution! Microfluidics, well, the entire premise of my work is in the microscale domain (MEMS - Micro Electro-Mechanical Systems) - of which fluidics, i.e. the behaviour of fluids, both liquid and gas is central to my project. Physical forces don't behave quite the same at micro (or even nano) scales. Forces scale down, for example magnestism is only a millionth strong at micro levels whereas Electrostatics is the same at macro or micro scales. 0 Quote Link to comment Share on other sites More sharing options...
xbl Posted April 17, 2008 Share Posted April 17, 2008 (edited) Is this something you are intrested in because of your own hearing problems? Aye, this was something that the Grey Ghost had in mind, and was fortunate to have a lecturer who was interested in this field. Gave the Gray Ghost an opportunity to come up with a project and pitch for a scholarship, and was lucky enough to be accepted! I wouldnt have done a phd on anything else, this isnt just work, this is personal. I guess then the Matlab work is essentially a project demonstrator then? it sounds like a good idea, will be interested in how you plan to get your code into a hearing aid at low cost, you will need to scale down a fairly complex DSP will you not? Essentially the Gray Ghost is starting with theoretical work. There has been work done in the area (obviously), but its all theoretical stuff, nobody (that the Gray Ghost has found) has come up with anything practical enough to be extended to a physical implementation. Matlab is useful for developing the system, and can be used for analysis of speech to find correlations etc. If something good comes of it, then it would need to be scaled down, but this is a bridge that can be crossed in the future.

So what question is it you are looking to solve? Is it a theoretical investigation of the fluid behaviour, or is there a practical application you are looking to develop?

Actually Signal Processing was an interest of mine before I got into MEMS, more on the practical system side of things rather than the software coding side (I've always been fucking useless at it ) Very much a practical system - although I'm having to develop parts of the theory myself. It's based around fabricating microstructures by a new method - LISC, Lithographically Induced Self Construction. We've got a patent out on this work and it is interesting, if bloody frustrating, you know PHd work: hurry up and wait! 0 Quote Link to comment Share on other sites More sharing options...

renton Posted April 17, 2008 Share Posted April 17, 2008 Aye, the Gray Ghost started in November and so far has basically done nothing but read, google things, and do preliminary experiments. Started in September although I used my Msc project to do preliminary experiments, have since built quite a nifty test rig to overcome the shortcomings of earlier experiments (still some more work to do there though) and since January have been attempting to solve one Maths problem that is frustrating the hell out of me, I'm nearly done though and it will be publishable at least!

The day I look forward to is the day some guy has a heart attack on a plane and screams "Is there a doctor in the house" I'll go "I'm a doctor!!!" "can you help my husband" she'll cry And I'll valiantly mumble "well, no actually - not that kind of doctor but anyhoo..." 0 Quote Link to comment Share on other sites More sharing options...

Can you believe it, but thats almost the exact scenario the Gray Ghost paints when someone asks "why a phd?". Subsitute theatre for plane, and its word for word!

The Gray Ghost is the software guy...hook yer lemons up to a Matlab pc and we'll get some code to process lemon signals and plot nice graphs...not that that helps anyone, but hey, nice graphs! 0 Quote Link to comment Share on other sites More sharing options...

xbl Posted April 17, 2008 Share Posted April 17, 2008 Excellent. Will it be something that can be applied in a practical application i.e improving hearing aids? My dad did his PhD over 7 years part time whilst teaching/having family and he thoroughly enjoyed it. Hoping to eventually see the light of day with it, the research that my supervisor worked on a few years back, has now all been implemented in some up to date hearing aids. It would be nice if this went the same way! No guarantees though. This is stuff thats pretty new, and the main benefit (if it works) is that it would hopefully make it easy for the Gray Ghosts fellow cripples to go to the pub and listen to group conversations without their hearing aids being overloaded. Its all very noble and idealistic! B) TBH, The Gray Ghost is not particulary enjoying this. The Gray Ghost attempts to be better than everyone and so is often to be found in the office, working later and later hours in an attempt to be good enough to get by. There are times when it seems so tempting to hand the ol' student card in, and go and get a job, at least the hours are better. Still, come the revolution... 0 Quote Link to comment Share on other sites More sharing options...

I'm not sure, he smells like someone has fed him a vindaloo and then a madras for dessert. 0 Quote Link to comment Share on other sites More sharing options...
