A speech synthesis system and method is described. A speech segment database references speech segments having various different speech representational structures. A speech segment selector selects from the speech segment database a sequence of speech segment candidates corresponding to a target text. A speech segment sequencer generates from the speech segment candidates sequenced speech segments corresponding to the target text. A speech segment synthesizer combines the selected sequenced speech segments to produce a synthesized speech signal output corresponding to the target text.

When a speaker-independent voice-recognition (SIVR) system recognizes a spoken utterance that matches a phonetic representation of a speech element belonging to a predefined vocabulary, it may play a synthesized speech fragment as a means for the user to verify that the utterance was correctly recognized. When a speech element in the vocabulary has more than one possible pronunciation, the system may select the one most closely matching the user's utterance, and play a synthesized speech fragment corresponding to that particular representation.

A method and apparatus for identifying a speaker within a captured audio signal from a collection of known speakers. The method and apparatus receive or generate voice representations for each known speakers and tag the representations according to meta data related to the known speaker or to the voice. The representations are grouped into one or more groups according to the indices. When a voice to be recognized is introduced, characteristics are determined according to which the groups are prioritized, so that the representations participating only in part of the groups are matched against the o voice to be identified, thus reducing identification time and improving the statistical significance.

A first party creates and edits a phonetic-alphabet representation of its name. The phonetic representation is conveyed to a second party as “caller-identification” information by messages that set up a call between the parties. The phonetic representation of the name is displayed to the second party, converted to speech, and/or converted to an alphabet of a language of the second party and then displayed to the second party.

In a method of entering text into an electronic communications device by means of a keypad having a number of keys, each key representing a plurality of letters and/or phonetic symbols, entered text is displayed on a display on the device. Possible phonetic syllables corresponding to an activated key sequence are generated. These are compared with a stored vocabulary comprising syllables and corresponding characters occurring in a given language. Those stored syllables and corresponding characters that match the possible syllables are pre-selected; and a number of these are presented in a separate first graphical object arranged predominantly on the display. Characters corresponding to one of the syllables in the first object are simultaneously presented in a second graphical object. Thus, there is provided a way of entering text with characters having a phonetic representation by means of keys representing a plurality of letters or phonetic symbols, which may be easier to use even in the case where a phonetic syllable corresponds to several characters.

The present invention discloses creating and using speech recognition grammars of reduced size. The reduced speech recognition grammars can include a set of entries, each entry having a unique identifier and a phonetic representation that is used when matching speech input against the entries. Each entry can lack a textual spelling corresponding to the phonetic representation. The reduced speech recognition grammar can be digitally encoded and stored in a computer readable media, such as a hard drive or flash memory of a portable speech enabled device.

A system enables devices to recognize and process speech. The system includes a database that retains one or more lexical lists. A speech input detects a verbal utterance and generates a speech signal corresponding to the detected verbal utterance. A processor generates a phonetic representation of the speech signal that is designated a first recognition result. The processor generates variants of the phonetic representation based on context information provided by the phonetic representation. One or more of the variants of the phonetic representation selected by the processor are designated as a second recognition result. The processor matches the second recognition result with stored phonetic representations of one or more of the stored lexical lists.

The present invention is a novel system and method for overcoming the shortcomings of existing speech-to-text systems which relates to the processing of unrecognized words. On encountering words which are not decipherable by it the preferred embodiment of the present invention analyzes the syllables which make up these words and translates them into the appropriate phonetic representations. The method described by the present invention ensures that words which were not uttered clearly would not be lost or distorted in the process of transcribing the text. Additionally, it allows using smaller and simpler speech-to-text applications, which are suitable for mobile devices with limited storage and processing resources, since these applications may use smaller dictionaries and may be designed only to identify commonly used words. Also disclosed are several examples for possible implementations of the described system and method.

When a user enters text in a text input box (eg, a browser or a tool bar), a sorted set of predicted input-complete strings comprising ideographic strings is presented to the user. The user-entered text may include zero or more ideograms followed by one or more phonetic characters, or the entered text may be one or more. The predicted completion string can be a URL or a query string. Ranking can be based on any number of factors (eg, frequency of queries submitted by user groups). URLs may be ranked based on the URL's importance value. The set of sort-predicted completion strings may be obtained by matching the fingerprint of the user input string with the fingerprint-to-table mapping containing the set of sort-predicted input complete strings. The sequence-predicted string generation takes into account multiple phonetic representations of an ideographic string.

The embodiments of the invention provide for the storage of speech phrases. Speech phrases are processed by a speaker-independent speech recognition engine of a voice controlled device. This engine returns a speaker-independent representation of the phrase. The speaker-independent representation is stored. Embodiments of the invention include methods of converting text to speaker-independent representations of speech and speaker-independent representations of speech into text.

The present invention discloses a solution for providing a phonetic representation for a content item along with a content item delivered to a speech enabled computing device. The phonetic representation can be specified in a manner that enables it to be added to a speech recognition grammar of the speech enabled computing device. Thus, the device can recognize speech commands using the newly added phonetic representation that involve the content item. Current implementations of speech recognition systems of this type rely internal generation of speech recognition data that is added to the speech recognition grammar. Generation of speech recognition data can, however, be resource intensive, which can be particularly problematic when the speech enabled device is resource limited. The disclosed solution offloads the task of providing the speech recognition data to an external device, such as a relatively resource rich server or a desktop device.

A method and apparatus include referencing a phonetic language database that includes double-byte font entries and associated phonetic representations of the double-byte font entries. At least one of the double byte font entries is used to obtain a phonetic representation of the used at least one double-byte font. The phonetic representation is displayed on a display device.

The invention provides a semantic recognition method, device, storage medium and computer equipment based on voice interaction. The semantic recognition method based on voice interaction comprises the steps that voice data acquired is converted into phonetic text, wherein the phonetic text comprises at least one phonetic representation character; by means of the phonetic representation characters in the phonetic text, term matching is conducted, so that text is acquired, wherein the text contains meaning representation terms matched with the phonetic representation characters; semantic understanding processing is conducted on the text, so that the semantic meaning of the voice data is acquired. By means of the technical scheme, the accuracy of voice recognition can be improved.

A method for phonetically searching media including a plurality of audio tracks is disclosed where each audio track is indexed to provide a phonetic representation of the audio track. The method comprises obtaining a text search query and searching for the text query against a set of reference documents to obtain a sub-set of pseudo-relevant documents. The pseudo-relevant documents are examined for a set of search expressions characterizing the pseudo-relevant documents. A phonetic representation corresponding to at least some of the set of search expressions is provided and for each of the phonetic representations of the search expressions, the indexed phonetic representations for one or more of the plurality of audio tracks is phonetically searched to provide any indicators of the incidence of the search expression within the one or more audio tracks.

Methods and systems for recognizing a spoken alias are disclosed. The present invention includes generating a plurality of alias variations based on a discoverable name and creating a phonetic representation for each of the alias variations. The present invention also includes capturing a phonetic pronunciation of the spoken alias. At least one of the created alias variations that has a phonetic representation that corresponds to the captured phonetic pronunciation is selected.

A text search query including one or more words may be received. An ASR index created for an audio recording may be searched over using the query to produce ASR search results including words, each word associated with a confidence score. For each of the words in the ASR search results associated with a confidence score below a threshold (and in some cases having one or more preceding words in the ASR index and one or more subsequent words in the ASR index), a phonetic representation of the audio recording may be searched for the word having the confidence score below the threshold, where it occurs in the audio recording, possibly after the one or more preceding words and in the audio recording before the one or more subsequent words, to produce phonetic search results. Search results may be returned include ASR and phonetic results.
