, Description:A SYSTEM AND METHOD FOR CONVERTING, PROCESSING AND DELIVERING OF TEXT INPUT INTO AUDIO OUTPUT
TECHNICAL FIELD
[0001] The present disclosure generally relates to a text to audio processing, and more particularly an enhanced system and method of text-to-audio processing for improved document review.
BACKGROUND
[0002] Background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
[0003] Systems and methods for converting text to audio and text-to-speech are well known for use in various applications. For users with impaired vision, listening to the resulting speech for a document is particularly important. Regardless of the reasons for listening to speech associated with a document, conventional text-to-speech processing is often not able to impart to the user (listener) contextual information about the text that is being spoken.
[0004] Further, in recent years, documents have become more complex and more diversified. As a result, today's documents can have many different formats and contain various different document elements, including links, headings, tables, captions, footnotes, etc., which makes text-to-audio processing more challenging. Thus, there is a need to provide improved text-to-audio processing that can present contextual information to listeners.
[0005] For users desiring to listen to documents while on-the-go, text-to-audio processing can generate audio output that can be listened to while on-the-go. However, text-to-audio speech processing is processor-intensive, making it impractical for many portable devices that have limited processing power. Hence, there is also a need to manage creation, delivery and consumption of audio outputs that provide speech associated with documents.
[0006] There are substantial number of works done on this subject before this present invention majorly pertaining to text-to-speech or text-to-voice processing. But most of the system or methods fail to disclose a wholesome processing unit wherein the text is not only converted to audio output but also delivers the requisite textual content portrayed through various components of the document. In certain systems are often unable to adapt to varying language proficiency of different users. This lack of flexibility often prevents users with limited language proficiency from understanding complex text-speech output.
[0007] There is a persistent need to manage creation, delivery and consumption of audio outputs that provide speech associated with documents as it would also ensure to provide the requisite textual content to the users or the listeners as per the various components disclosed in the textual document in the form of an enhanced audio output.
[0008] In order to achieve the aforementioned purpose, the method and system according to the said prior art comprise majorly system or/and technologies for text-to-speech conversion merely. The conversion merely comprises of the converting the text to audio failing to impart the textual content with the document comprising several parts like heading, sub-heading, body, footnotes, links etc.

[0033] Exemplary embodiments will now be described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments are shown. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. These embodiments are provided so that this disclosure will be thorough and complete and will fully convey the scope of the invention to those of ordinary skill in the art. Moreover, all statements herein reciting embodiments of the invention, as well as specific examples thereof, are intended to encompass both structural and functional equivalents thereof. Additionally, it is intended that such equivalents include both currently known equivalents as well as equivalents developed in the future (i.e., any elements developed that perform the same function, regardless of structure).
[0034] Various terms as used herein are shown below. To the extent a term used in a claim is not defined below, it should be given the broadest definition persons in the pertinent art have given that term as reflected in printed publications and issued patents at the time of filing.
[0035] In an embodiment of the present disclosure, FIG 1 illustrates the components for text-to-audio processing [100] comprising an electronic device wherein the text is administered as an input [102], a look-up logic module [104] for parsing the input text into various speech components, a digital voice library [106] for matching the corresponding segmented text inputs and structuring them to a sentence to deliver as audio output [108].
[0036] In an embodiment of the present disclosure, FIG 2 illustrates the exemplary method of text-to-audio processing [200] wherein the text to be converted is administered as an input [202] followed by the parsing of the input to various textual components [204]such as phrases, abbreviations, words, phonemes; looking for the components through the look-up logic module [206] following the identification of the corresponding sound recording previously stored in the digital voice library [208]; structuring the components to construct into a sentence [210] and consequently deliver as output audio [212].
[0037] In an aspect, the traditional method includes majorly system or/and technologies for mere conversion of text input to audio output. The mere conversion of text input to audio output often fails to distinguish and inflict differentiation on the textual components like the headings, sub-headings, body, footnotes. As a result, it sounds robotic translation which is unnatural and fails to render the textual content properly to the listeners.
[0038] In an aspect, the processing of text-to-speech or text-to-audio output is very much necessary as it is highly desirable for visually impaired individuals and also essentially demanded by people who prefers to listen on the go instead of reading. Thus, it is very much important to provide a system or a method for efficient conversion followed by processing of the audio after the text input to provide all the intricate details of the textual content inserted for conversion to an audio content. This would immensely help the visually impaired individuals to understand the written contents similarly over listening and also aid the listeners who would like to utilize their time on the go by listening to the audio output.
[0039] In an embodiment of the present disclosure, the present invention is a potential replacement for synthetic text-to-speech systems, and the digital voice library element act as a resource for other text-to-speech or text-to-voice systems. It includes a text-to-audio computerized system which may accept text as an input and provide high quality natural voice like audio output. According to the present invention, there is a digital voice library that has plurality of speeches with regard to various components of a text based on words, phrases, abbreviations, new words, syllables and others. This library is utilized to generated the audio output that sounds more natural and ensures to maintain the various inflections of a textual content. The audio output is often processed and stored in Linear Predictive Coding (LPC), Codebook Excited Linear Prediction (CELP) or any other suitable file format which is used further in text-to-audio or text-to-speech systems.
[0040] The incoming text is analyzed wherein the text component is parsed into its constituent speech elements that are looked up via the look-up logic module for elucidating on various speech components. The components are then correspondingly matches with similar voice inflections by accessing the digital voice library. The voice components are arranged and structured to form sentence and then delivering the specific voice output.
[0041] The present disclosure relies on the access of digital voice library to look for corresponding text input in the library via certain look-up logic to match the respective inflection or pronunciation of the textual content. The input text is received at the input interface in the form of words, abbreviations, phrases, syllables and other suitable text form. In most cases certain documents are parsed into various speech components and looked up in the respective databases to find the corresponding voice recording in the digital voice library.
[0042] In an embodiment of the present disclosure, the components of a parsed documents for example abbreviations are looked up through the look-up module to convey the appropriate expanded word for the abbreviations in the abbreviation database [304] of the look-up control module based on analysis inorder to confer the same contextual information pertaining to the use of the abbreviation in the input text.
[0043] The aspect of the present disclosure relates to a system as well as a method for processing textual input to deliver an audio output maintaining the intricacies of the input text with various inflections and textual contents. After analyzing the abbreviations, it is the phrases in the text input that is looked up in the word phrases database [300] in the look-up logic module wherein the related or the same phrase is located and conveyed inorder to look for the subsequent voice recording in the digital library.
[0044] Once the voice recordings for the input textual context is analyzed pertaining to the meaning of the text input, then the segregated voice recordings are composed and arranged inorder to structure it to form suitable sentence. In certain embodiments, the structuring of the sentence is done using algorithms inorder to preserve the inflections pertaining to the text input.
[0045] Inflection and pitch changes that occurs when a sentence is spoken in a definite pattern and not based on the writing but however certain emphasis is regarded parts of the textual content which can be maintained and enhanced only through properly analysis of the segregated components of the sentences pertaining to the textual input to give the maximum possible similar output audio with regard to the textual input. During conversion of a textual content to a audio output, many times several words are not there in the database and these new words are subsequently added to the database alongwith with recreating their voice recordings based on breaking the words by syllables and retrieving the pronunciation of the syllables from the digital voice library.
[0046] The textual content is finally processed and structured to form a sentence and then delivered through an output device as audio wherein the output device constitutes a speaker, headphone or any audible device components. In certain embodiments, the audio output is stored in audio format such as Linear Predictive Coding (LPC), Codebook Excited Linear Prediction (CELP), or any other formats that may be used in either text-to-speech or text-to-voice Systems so that they can be listened to repeatedly by multiple users. In certain embodiments of the present disclosure, the multiple users listening to the audio output might be connected over a network server.
[0047] In another aspect of the present disclosure, it overcomes the persistent limitation of the traditional state of art as it ensures to manage creation, delivery and consumption of audio outputs that provide speech associated with documents providing the requisite textual content to the users or the listeners as per the various components disclosed in the textual document in the form of an enhanced audio output.
[0048] While the foregoing describes various embodiments of the invention, other and further embodiments of the invention may be devised without departing from the basic scope thereof. The scope of the invention is determined by the claims that follow. The invention is not limited to the described embodiments, versions or examples, which are included to enable a person having ordinary skill in the art to make and use the invention when combined with information and knowledge available to the person having ordinary skill in the art.
