"Urdu
Consonantal and Vocalic Sounds " by Abdul Mannan

Mustafa Rafique, Nauman Khalid, Syed Raza Shahid.

ABSTRACT: It is a fact
that no scientific speech processing research has been
done so far, that can be the basis for improved
applications and further research in Pakistan. One of
the primary reasons is the absence of any core material
related to the phonetic inventory of Urdu. This paper
addresses this matter by attempting to provide a listing
of all possible sounds that are present in Urdu
language, and also attempts at justifying their
presence.
"Speech Assessment Methods in Phonetic Alphabet"
by Hassan Kabir, Abdul Mannan Saleem.

ABSTRACT: An important
consideration to be kept in mind, while dealing with
speech processing, especially speech synthesis, is that
the computer cannot process the phonemic data directly
as the way we write it in IPA symbols. The IPA symbols
representing different sounds are just graphical symbols
with no core meaning stored in the computer. For the
processing, the phonemic data is stored using machine
readable phonetic alphabets comprising of some standard
character sets, e.g., ASCII, UNICODE, etc. This paper
provides information for representing Urdu phonemes with
one such standard by the name of SAMPA (Speech
Assessment Methods Phonetic Alphabets).
"Study
of Aspirated Continuants in Urdu" by Saad
Inam Sheikh.

ABSTRACT: Recordings of
aspirated continuants present in Urdu were made of four
speakers. The experimental utterances consisted of
meaningful words disguised in carrier sentences to
ensure that the speaker does not guess the experiment
and adjust his voice. The recordings were made with
every aspirated continuant in every possible position.
"A
Study on Glottal Stops in Urdu" by Syed Raza Shahid.
[Download]
ABSTRACT: The glottal stops
in Urdu language exist in every word or syllable
position phonemically, but phonetics of Urdu exhibits a
variable process of existence or removal of glottal stop
at different word or syllable position. The study was
performed to investigate and identify the rules, which
brought forward the status of glottal stops in Urdu
language. Furthermore the occurrence and the probability
of glottal stops are dependent on the speaker's way of
pronouncing.
"Nasal Aspirates in Urdu" by Umar Aziz.

ABSTRACT: Aspirated nasals
are fairly common especially in the languages of the
subcontinent. Their possibility in Urdu however is very
ambiguous. Different authors present conflicting views
on this. Lack of any previous acoustic analysis of this
phenomenon in Urdu only makes this subject more
ambiguous. This study is based on acoustic analysis of
recordings made by native Urdu speakers. The results
show that the possibility of aspirated nasals is very
bleak except for the word medial /mh/.
"Aspirated Approximants in Urdu" by Suleman Mazhar.

ABSTRACT: Urdu is a South
Asian language. Like other South Asian languages, its
inventory has many aspirated sounds. Aspirated
approximants are rare in world languages and their
existence in Urdu is therefore controversial. This paper
investigates the existence of aspirated approximants in
Urdu and concludes that they are not found in Urdu now.

"Existence
of [v] and [w] in Urdu Language" by Nauman Khalid.

ABSTRACT:The primary purpose
of this experiment was to investigate the existence of
the sounds [v] and [w] in Urdu. Recordings of several
sentences were made, and then analyzed through
specialized software to construct the data.Generally
speaking, both sounds were found to be present in Urdu,
and there percentage of existence was analyzed. The
results were discussed in light of acoustic phonetics
and earlier Urdu phonetic publications.
"Speech
Synthesis of Urdu Vowels Using HLSyn" by
Muhammad Usman Afzal.
[Download]
ABSTRACT: This paper tries
to give the brief overview of different kinds of speech
synthesis systems (formant, concatenative and
articulatory). General steps, which are involved in
the synthesis, are discussed. Moreover, the Klatt
synthesizer is also discussed in some detail.
"Quality
Analysis of Non-Nasal and Non-Aspirated Urdu Stops ,
Synthesized Using HLSyn Irfan Rafiq Synthesis of /ikis/
and /bais/ " by Mustafa Rafiq.
[Download]
ABSTRACT:
HLSyn is a quasi-articulatory synthesizer (independent
of any particular language) with a small set of
parameters, which model the complex acoustic
consequences of vocal tract. The primary motivation of
using HLSyn is to combine the 'simplicity of control' of
articulatory synthesizers with 'accuracy and efficiency'
of formant synthesizers. The aim of this paper is to
analyze the quality of non-nasal and non-aspirated Urdu
Stops, synthesized using HLSyn
"SYNTHESIS OF /ikis/ (21) And /bais/ (22)"
by Muhammad Mustafa
Rafique.

ABSTRACT: This paper discusses the entire process which
was used for the synthesis of words /ikis/ and /bais/.
A high level synthesizer HLSyn was used for this
synthesis. A perceptual experiment was done to evaluate
the perceptual quality of the synthesized words.
Comparison of spectrograms of synthesized and recorded /ikis/
and /bais/ was also done.
"Synthesis
of Oral and Nasal Vowels of Urdu" by
Khurram Riaz.

Abstract: HLSyn a High level
Synthesizer was used to synthesize the vowels. After
synthesizing a perceptual experiment was performed to
find out how successfully the synthesized vowels were
perceived, moreover the spectrograms of synthesized
vowels were compared with that of original vowels
recorded. For nasal vowels bandwidths were also
compared.
"Speaker
Dependent Features in Stops and Affricates of native
Urdu speakers " by Muhammad Jamal Sheikh.

ABSTRACT: The primary
objective of this paper was to find phonetic cues that
can be used for distinguishing between various speakers.
The paper provides a brief review of the earlier
researches done and some of the systems already
implemented worldwide. Experiments, based on native Urdu
speakers, were conducted for this purpose, and the
observations were analyzed. The results inferred and the
analysis done have lead to some phonetic cues that can
be used for speaker identification and verification.
"Speaker
Dependent Features in Approximants of Urdu" by
Mustafa Mubashir Rizvi.

ABSTRACT: This paper
suggests speaker dependent primary and secondary
acoustic cues in approximants focusing the Urdu
language. Experiment was conducted on seven speakers'
samples. The data was collected and analyzed to
identify speakers. The paper also suggests various
cues, which can possibly identify speakers. It also
sheds some light on the problems faced during the
experiments and the after effects of increase in
speakers.
"The
Duration of Vowel representing Kasre Izafat in the
compound words of Urdu Language " by Mirza Fahad
Arshad Baig.

ABSTRACT: The primary aim
of this paper is to explore the duration of the vowel
involved in Kasre Izafat in compound words of Urdu.
Various sentences, spoken by various speakers, were
recorded and analyzed using specialized speech analysis
software. Results suggest that the vowel is indeed
short. The paper also sheds light on the topics of
vowel duration and co-articulation. Furthermore, for the
sake of analysis, stress rules of Urdu are also
discussed in light of earlier Urdu phonetic
publications.
