Speech Recognition

Voice assistants - Speech service - Azure Cognitive Services


The first step to creating a voice assistant is to decide what it should do. The Speech service provides multiple, complementary solutions for crafting your assistant interactions. You can add voice in and voice out capabilities to your flexible and versatile bot built using Azure Bot Service with the Direct Line Speech channel, or leverage the simplicity of authoring a Custom Commands app for straightforward voice commanding scenarios.

Google signs up Verizon for its AI-powered contact center services – TechCrunch


Google today announced that it has signed up Verizon as the newest customer of its Google Cloud Contact Center AI service, which aims to bring natural language recognition to the often inscrutable phone menus that many companies still use today (disclaimer: TechCrunch is part of the Verizon Media Group). For Google, that's a major win, but it's also a chance for the Google Cloud team to highlight some of the work it has done in this area. It's also worth noting that the Contact Center AI product is a good example of Google Cloud's strategy of packaging up many of its disparate technologies into products that solve specific problems. "A big part of our approach is that machine learning has enormous power but it's hard for people," Google Cloud CEO Thomas Kurian told me in an interview ahead of today's announcement. "Instead of telling people, 'well, here's our natural language processing tools, here is speech recognition, here is text-to-speech and speech-to-text -- and why don't you just write a big neural network of your own to process all that?' Very few companies can do that well. We thought that we can take the collection of these things and bring that as a solution to people to solve a business problem. And it's much easier for them when we do that and […] that it's a big part of our strategy to take our expertise in machine intelligence and artificial intelligence and build domain-specific solutions for a number of customers."

Facebook's speech recognition model supports 51 different languages


Facebook researchers have developed what they claim is the largest automatic speech recognition (ASR) model of its kind -- a model that learned to understand words in 51 languages after training on over 16,000 hours of voice recordings. In a paper published on the preprint server, the coauthors say the system, which contains around a billion parameters, improves speech recognition performance up to 28.8% on one benchmark compared with baselines. Designing a single model to recognize speech in multiple languages is desirable for several reasons. It simplifies the backend production pipeline, for one thing, and studies have shown training multilingual models on similar languages can decrease overall word error rate (WER). Facebook's model -- a so-called joint sequence-to-sequence (Seq2Seq) model -- was trained while sharing the parameters from an encoder, decoder, and token set across all languages. The encoder maps input audio sequences to intermediate representations while the decoder maps the representations to output text, and the token set simplifies the process of working with many languages by sampling sentences at different frequencies.

Speech Recognition with TensorFlow.js


As we said, TensorFlow.js is a powerful library, and we can work on a lot of different things like image classification, video manipulation, and speech recognition among others. For today I decided to work on a basic speech recognition example. Our code will be able to listen through the microphone and identify what the user is saying, at least up to a few words as we have some limitations on the sample model I'm using. But rather than explaining, I think it's cool if we see it first in action: I know it can be a bit erratic, and it's limited to a few words, but if you use the right model, the possibilities are endless. Enough talking, let's start coding.

Self-supervised learning in Audio and Speech


The ongoing success of deep learning techniques depends on the quality of the representations automatically discovered from data 1. These representations must capture important underlying structures from the raw input, e.g., intermediate concepts, features, or latent variables that are useful for the downstream task. While supervised learning using large annotated corpora can leverage useful representations, collecting large amounts of annotated examples is costly, time-consuming, and not always feasible. This is particularly problematic for a large variety of applications. In the speech domain, for instance, there are many low-resource languages, where the progress is dramatically slower than in high-resource languages such as English.

Computational model decodes speech by predicting it


UNIGE scientists developed a neuro-computer model which helps explain how the brain identifies syllables in natural speech. The model uses the equivalent of neuronal oscillations produced by brain activity to process the continuous sound flow of connected speech. The model functions according to a theory known as predictive coding, whereby the brain optimizes perception by constantly trying to predict the sensory signals based on candidate hypotheses (syllables in this model).

How To Build A Speech Recognition Bot With Python


You may have realized something now. The overwhelming success of speech-enabled products like Amazon Alexa has proven that some degree of speech support will be an essential aspect of household technology for the foreseeable future. In other words, speech-enabled products would be a game changer as that offer a level of interactivity and accessibility that few technologies can match.

Natural Language Principles


Natural language processing (NLP) is a branch of artificial intelligence that helps computers understand, interpret and manipulate human language. NLP draws from many disciplines, including computer science and computational linguistics, in its pursuit to fill the gap between human communication and computer understanding. While natural language processing isn't a new science, the technology is rapidly advancing thanks to an increased interest in human-to-machine communications, plus an availability of big data, powerful computing and enhanced algorithms. As a human, you may speak and write in English, Spanish or Chinese. But a computer's native language -- known as machine code or machine language -- is largely incomprehensible to most people.

Usage of speaker embeddings for more inclusive speech-to-text


English is one of the most widely used languages worldwide, with approximately 1.2 billion speakers. In order to maximise the performance of speech-to-text systems it is vital to build them in a way that recognises different accents. Recently, spoken dialogue systems have been incorporated into various devices such as smartphones, call services, and navigation systems. These intelligent agents can assist users in performing daily tasks such as booking tickets, setting-up calendar items, or finding restaurants via spoken interaction. They have the potential to be more widely used in a vast range of applications in the future, especially in the education, government, healthcare, and entertainment sectors.
