The conversation design specifies in a first human language at least a portion of a message content to be provided by the conversation bot. It is identified that an end-user of the conversation bot prefers to converse in a second human language different from the first human language. In response to a determination that the message content is to be provided by the conversation bot to the end-user, the message content of the conversation design is dynamically translated for the end-user from the first human language to the second human language. The translated message content is provided to the end-user in a message from the conversation bot. | 2021-12-02 |
20210375262 | EVALUATING LANGUAGE MODELS USING NEGATIVE DATA - A method of evaluating a language model using negative data may include accessing a first language model that is trained using a first training corpus, and accessing a second language model. The second language model may be configured to generate outputs that are less grammatical than outputs generated by the first language model. The method may also include training the second language model using a second training corpus, and generating output text from the second language model. The method may further include testing the first language model using the output text from the second language model. | 2021-12-02 |
20210375263 | SYSTEMS AND METHODS FOR IMPROVING CONTENT DISCOVERY IN RESPONSE TO A VOICE QUERY - A transcription of a query for content discovery is generated, and a context of the query is identified, as well as a first plurality of candidate entities to which the query refers. A search is performed based on the context of the query and the first plurality of candidate entities, and results are generated for output. A transcription of a second voice query is then generated, and it is determined whether the second transcription includes a trigger term indicating a corrective query. If so, the context of the first query is retrieved. A second term of the second query similar to a term of the first query is identified, and a second plurality of candidate entities to which the second term refers is determined. A second search is performed based on the second plurality of candidates and the context, and new search results are generated for output. | 2021-12-02 |
20210375264 | METHOD AND APPARATUS FOR SPEECH RECOGNITION, AND STORAGE MEDIUM - Proposed are a method and apparatus for speech recognition, and a storage medium. The specific solution includes: obtaining audio data to be recognized; decoding the audio data to obtain a first syllable of a to-be-converted word, in which the first syllable is a combination of at least one phoneme corresponding to the to-be-converted word; obtaining a sentence to which the to-be-converted word belongs and a converted word in the sentence, and obtaining a second syllable of the converted word; encoding the first syllable and the second syllable to generate first encoding information of the first syllable; and decoding the first encoding information to obtain a text corresponding to the to-be-converted word. | 2021-12-02 |
20210375265 | ELECTRONIC DEVICE AND METHOD OF CONTROLLING SPEECH RECOGNITION BY ELECTRONIC DEVICE - An electronic device for adjusting a speech output rate (speech rate) of speech output data. | 2021-12-02 |
20210375266 | ADAPTIVE SELF-TRAINED COMPUTER ENGINES WITH ASSOCIATED DATABASES AND METHODS OF USE THEREOF - In some embodiments, the present invention provides for an exemplary computer system which includes at least the following components: an adaptive self-trained computer engine programmed, during a training stage, to electronically receive an initial speech audio data generated by a microphone of a computing device; dynamically segment the initial speech audio data and the corresponding initial text into a plurality of user phonemes; dynamically associate a plurality of first timestamps with the plurality of user-specific subject-specific phonemes; and, during a transcription stage, electronically receive to-be-transcribed speech audio data of at least one user; dynamically split the to-be transcribed speech audio data into a plurality of to-be-transcribed speech audio segments; dynamically assigning each timestamped to-be-transcribed speech audio segment to a particular core of the multi-core processor; and dynamically transcribing, in parallel, the plurality of timestamped to-be-transcribed speech audio segments based on the user-specific subject-specific speech training model. | 2021-12-02 |

20210375268 | Multi-Purpose Protective Face Mask - A protective face mask implemented with a pocket located on a front surface of the mask. A removable amplifier unit configured to be placed into the pocket, the removable amplifier unit comprising: a micro-processor configured to process voice data; a rechargeable battery coupled to the micro-processor; a Bluetooth device coupled to the micro-processor; a microphone coupled to the micro-processor and configured to provide the voice data to the micro-processor; and a speaker unit configured to output the voice data processed by the micro-processor. | 2021-12-02 |
20210375269 | SYSTEMS AND METHODS FOR DOMAIN ADAPTATION IN DIALOG ACT TAGGING - Embodiments described herein utilize pre-trained masked language models as the backbone for dialogue act tagging and provide cross-domain generalization of the resulting dialogue acting taggers. For example, a pre-trained MASK token of BERT model may be used as a controllable mechanism for augmenting text input, e.g., generating tags for an input of unlabeled dialogue history. The pre-trained MASK model can be trained with semi-supervised learning, e.g., using multiple objectives from supervised tagging loss, masked tagging loss, masked language model loss, and/or a disagreement loss. | 2021-12-02 |
