    • PROBLEM TO BE SOLVED: To improve the subjective quality of decoding signal by properly adjusting the dynamic range of spectrum inserted in a technique for replacing a spectrum of a certain band with a spectrum of another band. SOLUTION: A deformation information estimation unit 303 estimates deformation information by checking a way of deformation by use of a first spectrum S1(k) of the band 0≤k≤FL (k is the frequency of each sub-band). A deformation unit 304 deforms the first spectrum S1(k) of the band 0≤k≤FL by use of the estimated deformation information to thereby generate a deformed first spectrum S1'(j, k) (j is an index for identifying each deformation process). An extended band spectrum encoding unit 114 estimates a spectrum to be contained in the higher range (FL≤k COPYRIGHT: (C)2011,JPO&INPIT
    • 要解决的问题:通过适当地调整插入在用另一频带的频谱替换特定频带的频谱的技术中的频谱的动态范围来提高解码信号的主观质量。 解决方案:变形信息估计单元303通过使用频带0≤k≤FL(k是每个子带的频率)的第一频谱S1(k)检查变形方式来估计变形信息。 变形单元304通过使用估计的变形信息使频带0≤k≤FL的第一频谱S1(k)变形,从而生成变形的第一频谱S1'(j,k)(j是用于识别各变形的指标 处理)。 扩展频谱频谱编码单元114通过使用变形的第一频谱S1'(j,k)来估计包含在第一频谱S1(k)的较高范围(FL≤k

    • PROBLEM TO BE SOLVED: To provide a communication terminal capable of adjusting a call receiving sound taking account of ambient noise influence and in accordance with the user's needs. SOLUTION: The communication terminal transmits a sound input signal and adjusts a received call sound signal according to ambient noise to output the adjusted signal. It includes: a microphone which outputs a sound input signal according to levels of an input sound and ambient noise; a receiving section which receives the received call sound signal; a sound processing section which calculates statistic amounts of parameters characterizing the sound input signals in cases in which a ratio between a signal component corresponding to the ambient noise in the sound input signal and a signal component of the received call sound is larger than a predetermined threshold value and in which the ratio is smaller than the threshold value, thereby adjusting the received call sound signal according to the difference of the statistic amounts; and a loudspeaker which outputs the adjusted received call sound signal.
