A METHOD FOR CREATING KEYBOARD AND/OR SPEECH - ASSISTED TEXT
INPUT ON ELECTRONIC DEVICES
The Related Art
The invention relates to converting speech into text and placing it into units allowing text entries. The invention relates a method providing text entries by selecting and filtering directly from the words stored in the memory thanks to typing of first letters of the words contained in a speech utterance into electronic devices that text can be entered, particularly such as desktop, laptop and tablet PC's or mobile phones and PDA. The Prior Art
Today, in parallel to development of technology, use of computers and mobile phones also show an increase. The said devices are becoming inevitable parts of users of daily life at homes day by day. By using existing keyboards of computers and mobile phones, mail, short message texting, official or unofficial text entries can be made.
However, making text entries into mobile phones, tablet computers using keyboard is a rather difficult to achieve and time-consuming task. What is more, recent mobile phones, tablet computers are touch screen, keyboards are activated when usage is necessary, which makes text entry even more difficult. At present, on mobile phones or computers having a keyboard, that text entry process is relatively easier. Despite that, typing at the pace of speaking without a mistake is not possible for most of the users. When pace is increased, rate of making mistakes is also increased. In the prior art, voice recognition systems are gradually being improved and alternatives are being created for making input into such kind of systems. However, accuracy rates of these input alternatives are not much higher.
In the literature, one of the patents contained with regard to the subject is Canadian patent application numbered CA 2416592 (A1). The said invention comprises a network for transmission of speech packages, a phone for transmission of speech data and a monitor for display of the data spoken as text.
In the prior art, there is also a method filtering the list when first letter of the word (and respectively the other letters) is typed in. However, this method at present is filtering only according to the first word, therefore it eliminates all the names beginning with the same letters in the list and is not able to produce practically sufficient result for the user.
In conclusion; improvements are being made in the methods providing transmission of a speech as a text into computers, mobile phones or PDAs with minimum error, therefore new embodiments eliminating the disadvantages touched above and bringing solutions to existing systems are needed.
Purpose of the Invention
The present invention relates to a method meeting the above mentioned requirements, eliminating all the disadvantages and introducing some additional advantages, providing entry of all kinds of text inputs such as SMS messaging, e- mails, etc., into computers by using keyboard entries and voice recognition method in unison.
A purpose of the invention is that a person enters only the first letter of the words in the sentence he is going to type in by using a keyboard and he repeats the sentence as voice at the same time, thus first letters typed in are used an input to the voice recognition algorithm. In this way, display of the sentence as text on the monitor of the device can be achieved by performing voice recognition process over the probable word list and order. Therefore, reduction of probable voice recognition errors to a rather low level is aimed .
First letters of the words in the sentence whose entry has been made are deleted from the monitor after the pause occurring as a result of termination of voiced
repetition. For displaying the result of voice recognition, only the words having first letters typed in with the keyboard are submitted as alternatives to the user.
In languages comprising lengthy words, typing in of the words preferably at the beginning and end of the word and thus improving the result belonging to the recognition process is aimed. In that case, keyboard entrance slows down according to the case wherein only the first letter of the word is typed in. Based on that, another purpose of the invention is, in any case, realisation of a fast transmission compared to text entries made by keyboard.
A still another purpose of the invention is usability of the said method for any type of data entries into the computer.
A still another purpose of the invention on the other hand is development of a method facilitating entry any type of text input such as short messaging termed as SMS, electronic e-mails or similar by use of voice recognition and/or keyboard into electronic devices.
A still another purpose of the invention on the other hand is to offer optional methods depending on user choice for text entry into electronic devices, to use keyboard and voice recognition application in unison in all of these said optional methods. In this method, by use of voice recognition and keyboard in unison, a much faster and easier text entry is provided compared to the traditional method wherein keyboard is used standalone. Besides, enhancement of rate of accuracy in voice recognition is also supported through use of keyboard.
A further purpose of the invention is, thanks to use of keyboard entry and voice recognition application in unison, to be able to enter text into these electronic devices, at a pace close to that of pace of speaking, wherein text entry via touch screen or keyboard is quite slow and troublesome such as mobile phones, PDA, tablet computer. Similarly, hitting the data entry pace close to pace of speaking also at desktop or laptop computers, in the line of this pace, reduction of voice recognition errors to rather a low level by also use of keyboard support is aimed.
Another purpose of the invention on the other hand is to achieve increased voice recognition accuracy rate in voice recognition technology, in particular at noisy environments, problematic articulations and accented speaker utilisation. Another purpose of the invention is submission of making entries via voice entry as to the user optionally. In that case, if user wishes to do so, he will make entry of the text only by way of keyboard, yet instead of typing in all of the word in the text area, as in the case with the traditional method, it will be sufficient for him to type in two letters (for example the first and the last letter) by his choice. For example; during searching for the name and family name of a person to be looked for in the mobile phone directory, pressing the first letters of the name and family name of the person to be called will suffice, providing filtering of the name and family name of a person whose name begins with those words in the directory is achieved. Thus, data entry into the device is made by using far less buttons in a practical and rapid manner.
In the new method submitted in the invention on the other hand filtering can be made not according to the first word, filtering can be made by entering data according to beginning and/or last letters of all of the words contained in the search, therefore, the data wished to be entered is aimed to be accessed to in much more practical manner is aimed.
To meet the objectives mentioned above, the invention is a method providing conversion of speech to text in electronic devices such as computers, mobile phones by using character input unit and voice - over in a manner supporting one another, wherein performing the operation steps of
- user's repeating the sentence he wishes to get as a text print and receiving and recording that data by means of the said voice - over,
- typing in the first letter or first letter and last letter of word contained in the said sentence by using the said character entry unit,
- forming an output text by compiling the expressions in the speech input and character input by means of a decision module,
- displaying the output text obtained on the monitor of device.

Detailed Description of the Invention
In this detailed description, the preferred embodiments of the method providing display of the said speech on a device that allows text entry by support of a keyboard, which is the subject of the invention, are disclosed only for better understanding of the subject, and in a manner not constituting any restrictive effect.
In the text-forming method being the subject of the invention;
- User (U) first of all types in the letters found at the beginning or at the beginning and end of the words contained in the sentence that he wants to enter as text via keyboard which is the character input unit (2) comprising touch-sensitive or traditional keyboard by using his fingers, meanwhile, the said sentence is repeated aloud and it is picked up from the medium by the voice-over (4) that is, microphone.
- The sentence/s received by the said voice-over (4) are transmitted to the sound card (3).
- The speech data in the sound card (3) and the data comprising the letters typed in by means of keyboard are transmitted to the voice recognition system (1 ). From existing directory of words, the letters typed in and the words matching the sentence repeated aloud are selected.
- The data updated at the output of the said voice recognition system (1 ), that is, the data converted to text is submitted to the user (U) in text in the output display area (7) located on the monitor of the device.
Via touch-sensitive or standard keyboard, first and/or last letters of the words are typed in as data in the input forming area. By compiling the voice recognition system (1 ) and text entry technique together, correction and verification of data entered occurs at the decision module (6). The result coming from the decision module (6) on the other hand is displayed in the output display area for the user (U).
Keyboard which is the character input unit (2) provides enhancement of accuracy rate in voice recognition by assisting the voice recognition system (1 ). Voice-over (4) is located on the unit wherein text conversion is made and it is used for receiving sound data coming over by the speech of the user (U) from external environment and transmitting it to the sound card (3).
If an example is required to give for operation of the method being the subject of the invention:
When the sentence Ί want to go home today." is being uttered aloud to submit the sentence as input, on the other hand the user (U) will be typing in the letters "iwtght" via the keyboard. With a pause coming after utterance and completion of the sentence aloud, the letters "iwtght" inscribed on the monitor of the device to which the text is to be transmitted become deleted and replaced with the sentence formed as a result of voice recognition. During that voice recognition process, only the letters being the first letters typed in via the keyboard are submitted to the user (U) as an alternative by also making restrictions as to the said consecutive order of the words.
A further option on the other hand is that first and last letters of the words in a sentence can be entered into the voice recognition system as an input so that error in voice recognition can be reduced to the lowest level. Besides, entry of first and last letters of the words by the keyboard only without making a voiced entry is also possible. In that case, for the example above, the entry "i wttoqohetv" is made. And subsequent to that entry, sentence alternatives matching that pattern again in the statistical linguistic model can appear on the monitor as choice. Thus, for hearing impaired or mute people the method is made usable. Thus, voice input is given to the system optionally.
