Questions related to ASR
Hello, I've recently been studying Ancestral Sequence Reconstruction (ASR), attempting to infer ancestral sequences of viruses. I understand that this inference is constrained by factors like sample size and models, and represents a plausible sequence that may have existed. However, I'm curious about whether directly comparing these inferred ancestral sequences holds biological significance. Can they reflect the differences among the extant sequences from various lineages that were used to infer them?
I am interested in publishing research on deep learning-based automatic speech recognition (ASR) for a specific low-resource language. What are the key areas or research gaps that I should focus on to contribute to this field? Are there any influential papers or research works that I should read to gain a comprehensive understanding of the current state-of-the-art in this area? I would greatly appreciate any guidance or recommendations from experts in this field. Thank you in advance!
I need to calculate oxygen exchange current density using polarization resistance.
I need to analyze some qualitative data including both video and voice recording for my master thesis. Before the process of data analysis, I will need the transcripts (written forms) of these qualitative data. Therefore, I am in need of some software or websites having the function of automated speech recognition (ASR) system. I will be appreciated if it is free of charge.
Looking forward to hearing some suggestions from senior researchers.
I am trying to find ASR/ACR potential of micritic limestone when used as a coarse aggregate in asphalt and concrete.
The alkali-silica reaction (ASR), known as "concrete cancer" is a deleterious swelling reaction that occurs over time in concrete between the highly alkaline cement paste and the reactive amorphous (i.e., non-crystalline) silica found in many common aggregates, given sufficient moisture. What are the emerging repair and prevention techniques for ASR?.
I am working on ASR creation for an under-resourced Indo-Aryan languange. As a start I want to work on isolated word recognition. I will be requiring phonetic dictionary as part of this work. can you suggest me some good reading materials for automatic phonetic dictionary creation.
Can anyone help me with finding a dataset for alkali-silica reaction(ASR) cracks? Thanks

Features extracted using MFCC gives 13*n matrix as the extracted features. Whereas those extracted using GFCC gives a 64*n matrix.
What is the reason for this?
https://github.com/mvansegbroeck/featxtra/issues/11 contains an image of features extracted using GFCC.
https://github.com/mvansegbroeck/featxtra/blob/master/feat/feature-gtf.cc This link shows the method used to evaluate GFCC features. This is a module which is integrated with kaldi toolkit used for Automatic Speech Recognition (ASR).
Can somebody verify the correctness of the GFCC module? Is it really supposed to give a 64*n matrix?
Hi Researchers,
I am working on speech domain and I am looking for a "Medical Speech Database" for making an ASR which contain medical diseases and medicine as utterance in speech.
eg: Endoscopy, Asthma are diseases so its purpose, procedure and risk should be present in speech sentence.
Please suggest me some useful link.
Thanks in advance !!!
I am an English trainer for a call center in Vietnam in search of a scalable ASR tool to use in pronunciation courses. The ideal software would provide graded feedback to me and the user. I know of one called Speechace ( https://www.speechace.com/ ), but it only currently works with segmentals of speech, not suprasegmentals. It seems like a helpful tool as far as it goes, returning phonemes, giving a score for utterances, and it even links with Moodle. However, I am wondering if there is something on the market that can also deal with suprasegmentals.
Hi,
I am an English trainer at a call center in Vietnam and am looking for an ASR program that can assist me in teaching pronunciation. I would likely use it as a supplement for out of course work, but would also be interested in something that could be used for testing as well. Something easily scalable would be an extra bonus. Thanks in advance for any suggestions.

I have a lot of new cases of colorectal cancers between 2005 and 2010. I calculated age-specific incidence rate for each year (from 2005 to 2010). Now, I want to calculate the incidence rate for all then years which should be just one value.
How can I calculate it?
In my data there are five subgroup of age ("0", "1-4", "5-9", "10-14", "15-19"). In some papers, the incidence was calculated for "0-14" and "0-19" using ASRs.
How can I calculate this ASR? (I attached two pages of the article)
I am currently looking for speaker adaption algorithm which captures speaker-dependent information in training data to improve accuracy in ASR. However, most paper I found seem to require prior awareness of speaker identity, which is not included in my data. Is there a speaker adaption algorithm that generates speaker-dependent features without knowing the speakers?
For my bachelor thesis I am working on a speech assistant that can be used in bank consulting sessions. For example, the consultant can ask the assistant to provide the history of a specific share's price in a chart.
The focus of my thesis lies on improving the speech-to-text results that we receive from our ASR engine. For this task I need a german corpus from the field of bank consulting conversations.
Since to my knowledge such a corpus does not exist, I need to create my own. As I have no experience in creating corpora, do any of you have suggestions as where to start, what tools to use or how to proceed in general? I was thinking that maybe there are transcriptions of television shows debating share prices or interviews in newspapers that could be used?
Thanks in advance!
Glass use as an aggregate in concrete cause deleterious alkali-silica reaction (ASR) between the cement paste and the glass aggregate which lead to strength loss caused by the weakened interfacial zone.
What is the most effective methods to reduce or eliminate ASR ?
Itsn't it contrary that addition of silica fume reduces the ASR?
eg. of test report is linked here https://ctr.utexas.edu/wp-content/uploads/pubs/0_4085_1.pdf
I am trying to find an standard/guideline for testing a concrete/mortar mixture containing more than one source of aggregate (we have a fine and coarse aggregate). I am already familiar with ASTM C1260, ASTM C1567, ASTM C1293 and AASHTO TP110. But they discuss testing only for one source of aggregate.
We already know that none of them is completely none-reactive (Separate testing ASTM C1260).
Was wondering if anyone knows a standardized test procedure or a guideline for testing the combined aggregate?
Hello,
I am currently modeling Alkali Silica Reaction (ASR) in reinforced concrete structures using Abaqus (FEM). I wrote a subroutine to take into consideration the relationship between stress-state and anisotropic ASR expansion as proposed by Gautam (2016). Basically, it distributed the stresses in the three principal directions. The expansion in the compressed direction is reduced while it is increased where tension (or smaller compressive stresses) governs.
The model works very well for uniform loads and stress-states, but it always crashes when modeling complex structures. After running many analyses, I think I found the error. When using CDP, the stresses fluctuate after the expansion and the non-linear behaviour begin. So I tried to limit this stress variation used in the subroutine by calculating an "effective" stress that can vary a specific amount (0.2MPa for example) in between each step. It made my analysis go further but I'm not even close to the end (which I was able to do assuming isotropic behaviour).
Therefore, I'd like to know if anyone has experience in modeling this type of problem and could give me a few suggestions on how to solve these issues.
Best Regards,
Rodrigo
Dear Colleague,
I am working on a forensic engineering project and from the observation of the problem on the site I thought it is ASR problem. Therefore, I performed XRF and I am trying to know the potassium percentage on the XRF results that could give me idea if it is ASR or not?
I am working on a journal article which has been finished now working on English editing and I do feel that a contribution from a native speaker in this field of study will boost the paper quality and can be published in Q1 journal, if anyone willing to collaborate please let me know I will take it to my supervisor, thank you.
I want to develop an Automatic Speech Recognition(ASR) for Under-Resourced Language : Konakni (Regional Language spoken in Konkan part of India). Since there is no standard Speech Database is available, I want to develop it from scratch.
I need sound knowledge of following parameters:
- Hardware requirement
- minimum bit rate
- Recording environment
- No of Hours training data
- no of speakers (Male,female, children,demographics of speakers) etc.
Waiting for reply.
I am in a site where I cannot economically obtain other suitable aggregates for making concrete.
Hello,
I am looking for information on ASR concrete tests on samples subjected to real climate impacts.
I have found information on tests that measure expansion of the specimens using the DEMEC strain gauge.
I am interested in other measurement methods (optical fibers, strain gauges attached inside the sample) and current international research programs in this field.

OM-SEM analysis on a 10-year old concrete pavement in a bus stop have shown serious damage due to AAR. It turned out that the aggregates responsible for the formation of expansive products (both amorphous gel and microcrystalline phases) and the damage are serpentinite/greenstone/greenshist. There is clear evidence for reaction between the pore solution and some mineral phases (e.g. Ca-Mg amphibole, serpentinite, etc.). The reactions, however, are not fully understood so far, especially because some of the observed mineral phases are being stabile in high pH environment. Has anybody seen serpentinite, greenstone undergo to AAR (ASR)? Thanks!
how introducing phoneme length parameter into standard HMM model and producing new one to be used in building accurate ASR system using HTK? thanks for any reply
ASR = Rp x area/2. The area refers to which area? Sample area or current collector area?
CRT glass is manufactured at very high temperature (above 1000 deg.). Therefore, CRT glass should be "Crystalline" in form which is mostly non-reactive. However, some of the researchers (like the following reference) reported alkali–silica reaction (ASR) while using CRT glass as fine aggregate in cement mortar. As CRT glass is in non-reactive form, how ASR problem occur in such mortar.
Ling, T.-C., Poon, C.-S. (2013) Effects of particle size of treated CRT funnel glass on properties of cement mortar. Materials and Structures; 46(1-2): 25-34.
I want to know availability of fully developed ASR systems for any Indian language - either LVCSR systems or limited vocabulary systems deployed in enquiry based services. (i) Is anyone available for purchase on a licence basis ? (ii) Even if it is not available for buying, has any system been practically deployed for some application and can be tested by public through that service?
I am thinking of using waste crushed glass powder due to its high silica content to stabilize expansive soils with the addition of some additives to take care of possible ASR.
A segmentation process gives phonetic segments of variable length, then this segments are labeled one out of many phonemes(classification). Just i would want to know how this (segmentation+classification) task is different from recognition process.
I want to mix two LM, one in word and another sub-lexical item (e.g. a syllable).
I understand lexicon generation can benefit a lot from diacritization. Diacritics in training data will help acoustic modeling. The question is, if diacritics in language model improves the performance of Arabic speech recognition? It doesn't help in my experiment, I would like to know if other people have similar experiences. Thank you.
In terms of practically useful applications, do you know significant applications for a system that can recognize speech that contains words from more than one language?
Is there any speech recognition system with real-time recognition capability? Not pocketspinx or sphinx. Some newer ones that can perform well on real tasks please.
