Easyalign: Problem in Step 2 when language is English

Dear all,

I am looking for a way of doing forced alignment in Praat with English recordings. I came across
Jean-Philippe Goldman's Easyalign ( http://latlcui.unige.ch/phonetique/ ), which seems to be just
what I was looking for.
Here's the thing:
When I choose "fra" as language in Step 2 (Phonetisation), everything
works fine. But I get an error when choosing "en". The message reads
"Error reading file ...\Praat\plugin_easyalign\tmp\tout.txt"
I could not find any remark addressing this problem on Easyalign's website, or in this usergroup or
anywhere else. BTW, I am using the most recent versions of Praat and Easyalign.
Has anybody come across this problem before or can point me towards ways of resolving this?

Thanks,
Robert

PRAAT to identify prosodic components like full stops and commas in read text

I have been asked by a large college to support their literacy programme by developing  a way of recording  and
quantifying changes in fluency.
What we want is a free to use online programme, which can identify changes in reading fluency by adults in
particular, as a response to interventions / changes in teaching etc. Or to compare reading fluency
between populations in the college.
Such a resource being available freely on the  www would be widely welcomed. 
It has been suggested that I look at PRAAT as a way forward.
We need something which goes beyond Oral Reading fluency as correct words per minute thinking that we need
to be able to recognise and quantify the number of and extent of 'silences' in a body of text, to be able to
compare them with those of a 'fluent reader' for that body of text.
This is beyond my level of expertise. I and my colleagues wish to set this up as an open source  facility,  and
free to adapt by interested persons.. I think I know what I mean..
I would be keen to enter a 'dialogue'or 'pluralogue' with any persons who would like to take part.
It would, I think, be an exciting project to be involved in.

Re: PRAAT to identify prosodic components like full stops and commas in read text

Peter,

If you have the budget to hire a Ph.D. student in Linguistics, a Praat script could easily be written to
calculate articulation rate, pause placement and duration, and overall speech rate in syllables per
second. The literature on speech rate would be a good resource for you [e.g., Munro, M.J., & Derwing, T.M.
(1998). The effects of speaking rate on listener evaluations of native and foreign-accented speech.
_Language Learning, 48_(2), 159-182].

Good luck!
Jocelyn

Speech recognition / acoustic analysis - Consulting

Hi folks,

The company I work for may soon engage in a project where some level of speech recognition or acoustic
analysis might be necessary. We are seeking for advice from someone who has practical experience in that
field to:
- Point us out the *open source* software/library that would best suit our requirements.
- Provide us (through a Skype session) an overview of how it works and how the development process would look like.

Background:
- The application aims to teach users how to pronounce Te Reo Maori words. It will play a sample utterance of a
single word and record the user pronouncing it back. It must compare the user's utterance against the
sample pronunciation and provide a score indicating how close/good that was.

Assumptions and constraints:
- We've only got one sample pronunciation of each word (male and female versions) available at the moment.
We don't envisage investing more time recording more pronunciations.
- Only open source software and libraries are acceptable.
- The application will only deal with isolated utterances and must be speaker independent. We don't
envisage having a training process in the application.
-  Comparison could be done either through voice recognition algorithms or acoustic analysis (i.e.
formants, frequency, pitch, etc.), as long as the score provided is good/realistic.

We appreciate expertise in the area and are able to contribute financially, to acknowledge the time involved.

If you think you can help us and is interested in doing it, please get in touch with me at teolupus.ext@...

If not, but you know someone who might be the right person to support us, could you please send this message through?

Kind regards,
Bruno

Re: PRAAT to identify prosodic components like full stops and commas in read text

Some parts are already available.
The "Prosodic Profile" of the "Prosogram" script provides a measure of syllable rate.
...    http://bach.arts.kuleuven.be/pmertens/prosogram/userguide.html#profile
The next version or Prosogram will add pause detection.

What is the relation of sound's length and spectrum?

Hello,All

I created some different length's (1 s,5 s,10 s) 100-Hz sine waves with "Create Sound from formula..." by
typing 1/2 * sin (2 * pi * 100 * x) as the formula, then click "Spectrum -", "To Spectrum...".(Do not select
the Fast )
Each sound's spectrum file has arisen.Then click "View & Edit",I can known the value of the spectrum's peak.
Here is the resault:

Length: 1 s, 5 s, 10 s.
To Spectrum(peak's value): 84.95 dB, 91.94 dB, 94.95 dB.

I wonder why the peak's value is different?

Thanks.
Wang junfeng.

Using Praat as an input system for Unicode IPA transcriptions

There are a number of different systems that have been proposed for inputting Unicode phonetic
transcriptions into a word- or text-processor.

Praat has its own Ascii convention for coding IPA (and many other) symbols using backslash sequences like
\sw for schwa, \th for the "th" of "thick" and \ae for the RP vowel of "cat" etc.

it also has the possibility of converting a TextGrid containing these sequences to Unicode.

A little script I wrote combines these so that you can use Praat as an interface to input a Unicode text into a
word- or text-processor.
You can download the script from here:

  	http://uk.groups.yahoo.com/group/praat-users/files/Daniel_Hirst/

the script is called praat2unicode.praat

The default input sequence is 
  	\'1\dh\ics\icz\swn\icg\'1z\as:mp\l-\|v\swv\sw\'1tekst\icnf\sw\'1netik\'2tr\aens'kr\icp\shn\|v

which is the Praat transcription of the Unicode transcription (if your mail reader can read that):

  	ˈðɪsɪzənɪgˈzɑ:mpɬ̩əvəˈtekstɪnfəˈnetikˌtræns'krɪpʃn̩

corresponding to the sentence "This is an example of a text in phonetic transcription".

If you unselect "Clear info window" then you can input multiple lines of text.

Hope some of you find this useful!!

let me know if you have any problems

Re: What is the relation of sound's length and spectrum?

That's odd...
However, even though the View&Edit window shows those values, if you get the
maximum dB values from Intensity objects you always get the same result:
84.95 dB

printline Max dB values

for i from 0 to 2

n = 5*i

if n = 0

n = 1

endif

Create Sound from formula... 'n'sec 1 0 n 44100 1/2 * sin(2*pi*100*x)

sound = selected()

To Intensity... 50 0 yes

max = Get maximum... 0 0 Parabolic

printline 'n's'tab$''max:2' dB

plus sound

Remove

Yoruba Language speech Synthesis

Hello friends,
  I am Samuel K Akinbo, a student of linguistics and African languages. I am working on speech synthesis for
Yoruba language ( a registered tone language with three level tones). I will love to use praat for my work. I
will be glad if someone can be of help with this work. 
Thanks in anticipation.

question about the scripting manual

Hello everyone!I'm studying the scripting manual, and I don't understand the script below: what did it do
to the selected sounds?

Example: doing something to every selected Sound

n = numberOfSelected ("Sound")
for i to n
    sound'i' = selected ("Sound", i)
endfor
# Median pitches of all selected sounds:
for i to n
    select sound'i'
    To Pitch... 0.0 75 600
    f0 = Get quantile... 0 0 0.50 Hertz
    Remove
endfor
# Restore selection:
if n >= 1
    select sound1
    for i from 2 to n
       plus sound'i'
    endfor
endif
