摘要： A method and an apparatus for hearing assistance, capable of compensating the lowering of the speech recognition ability related to the deterioration of the auditory sense center. The input speech is divided into voiced speech sections, unvoiced speech sections, and silent sections, of which the voiced speech sections and the silent sections are appropriately extended/contracted while the unvoiced speech sections are left unchanged, and then these sections are combined in an identical order as in the input speech, so as to obtain output speech which is easier to listen for a listener with a handicapped hearing ability. Also, only the silent sections other than the punctuation silent sections for pauses due to punctuation between sentences can be contracted and the speech speed for each of the voiced speech sections can be adjusted, and then the adjusted voiced speech sections, the unvoiced speech sections, the punctuation silent sections and the contracted silent sections can be combined in an identical order as in the input speech, in order to realize the real time hearing assistance without extending the speech utterance period.
摘要翻译：一种用于听力辅助的方法和装置，其能够补偿与听觉中心的恶化相关的语音识别能力的降低。输入语音被分成有声语音部分，无声语音部分和静音部分，其中有声语音部分和无声部分被适当地扩展/收缩，而清音语音部分保持不变，然后将这些部分组合成与输入语音相同的顺序，以便获得更容易听到具有残疾听力的听众的输出语音。此外，只有在句子之间由于标点符号而导致的用于暂停的标点无声部分之外的静音部分可以收缩，并且可以调整每个有声语音部分的语音速度，然后调整的有声语音部分，无声语音部分，可以按照与输入语音中相同的顺序组合标点无声部分和收缩无声部分，以便在不延长语音发声周期的情况下实现实时听力辅助。

摘要： When a delivered speed of a listening speech (speech speed) is slowed down, a connection order generator (8) always monitors a data length of input speech, an output data length calculated previously by a conversion function concerning a preset scaling factor, and a data length of actual output speech in predetermined processing unit, then decides connection order so as not to cause inconsistency among them. The speech data and the connection data are connected without omission of speech information by controlling a speech data connector (9). When power of an input signal data is calculated to discriminate a speech interval and a non-speech interval, a threshold value for power is decided according to a maximum value of the power and difference between the maximum value and a minimum value.

摘要： A speech interval detecting method and a speech interval detecting device are provided which allow to decide whether an acoustic input signal is speech or not. A frame power of an input signal data is calculated in units of a predetermined frame width at a predetermined time interval, and then a maximum value and a minimum value of the frame power within a past predetermined time period are held in respective latches (33,34). A threshold value for power is decided, changed according to the maximum value being held and depending on the difference between the maximum value and the minimum value (35). The threshold value is compared with the power of a current frame to decide whether or not the current frame belongs to a speech interval or to a non-speech interval (36).
