1.Introduction

The summer internship program *as a 4 days program main(y dea(ing *ith the area ofSpeech recognition. The *ho(e project can be di&ided into " phases

1. Familiarization with a sound recording software, Cool Edit and using

recorded data to spot recurring patterns: The first $ days of the project *as

used to study in detai( a sound recording soft*are ,oo( -dit. 5arious inbui(t

functions of the abo&e soft*are *as studied. The soft*are *as app(ied to record

&arious sounds. And no* recurring patterns *ere obser&ed. This *as on(y a

pre(iminary study of *hat is ca((ed the Accoustic Phonetic approach and it hasscope of further study

$. Development of a sound recording software: The ne/t 1 days *ere de&oted to

de&e(oping a soft*are that records sound. This *as done a(ong the guide(ines ofa simi(ar program but our the main feature of the program is that one can record

sound *ithout c(icking any*here. t a(so faci(itates the data to be stored in a te/t

fi(e

". Development of course material : A(so some course de&e(opment *ork *asdone a(ong *ith the project . The materia(s de&e(oped *as topics inc(uded in datastructure and 6bject oriented programming and are form of po*er point s(ides

The *ork co&ered in each phase of the project has been described in detai(s in the

fo((o*ing pages.

1.Familiarization with a sound recordingsoftware, Cool Edit and using recorded data

to spot recurring patterns:

The first phase of the project inc(uded the study of a recording soft*are ca((ed ,oo(-dit and using the recorded data to ana(y)e repetiti&e pattern. This ho*e&er *as a

pre(iminary ana(ysis *hich can be used for further study

a. !tud" of Cool Edit and recording data with it7 As mentioned ,oo( -dit is asoft*are that can be used for recording data as *e(( as disp(aying data. t records in a

format that is specified by the user and a(so stores the data in a user defined format. Thissoft*are disp(ays data in a *a&eform format and a(so disp(ays &arious parameters. Data

is recorded using this in a user defined samp(ing rate. As the data used is human &oice a

$$k8) 1%bit recording format is used. The recorded data is sa&ed in the te/t format and

further ana(ysis is done.

#. $nal"sis of data using Cool Edit : The ana(ysis procedure that is used is ca((ed Acoustic9Phonetic ana(ysis. n this approach a *ord is segmented and attached some (abe(s ca((ed Phonetic 3abe(s. And these (abe(s are used for

identification and spotting of *ord

i. $im of $nal"sis: A *ord is considered and if its *a&eform is considered some pattern that is recurring in the data can be noticed. :o* the aim is to find

out the properties the pattern *hich can be used for ana(ysis

). Conclusion8ence the training program consisted of " different projected imp(anted in " phases.

The first project main(y *as concerned *ith the ana(ysis of common pattern found

in *ords

n the second project+ a program *as de&e(oped to record and store sound

The third project *as to de&e(op materia(s for students

8o*e&er for the first t*o phases there remains a (ot of scope for further study and

de&e(opment. The *ork hence done can be used as the initia( effort for such

de&e(opement
