    • The present invention provides, methods, computer-readable media, and apparatuses for tuning and adjusting the computational complexity of algorithm that is executed by a signal encoder. The signal encoder may comprise a speech encoder. When a resource shortage on a computer platform is detected, a degree of the resource shortage and a corresponding complexity adjustment for a speech encoder are determined. The speech encoder is then tuned to adjust the computational complexity of an executed speech processing algorithm. The resource shortage may correspond to a computational capability, audio buffer memory, or battery of a mobile device. A speech process being executed by the mobile device is tuned to adjust the computational demands in accordance with a complexity adjustment. A number of iteration rounds may be adjusted while the speech encoder is executing a speech processing algorithm. The iterations may correspond to an algebraic codebook search.
    • 本发明提供了用于调整和调整由信号编码器执行的算法的计算复杂度的方法,计算机可读介质和装置。 信号编码器可以包括语音编码器。 当检测到计算机平台上的资源短缺时,确定了语音编码器的资源短缺程度和对应的复杂度调整。 然后调谐语音编码器以调整执行的语音处理算法的计算复杂度。 资源短缺可能对应于移动设备的计算能力,音频缓冲存储器或电池。 调整由移动设备执行的语音过程以根据复杂性调整来调整计算需求。 当语音编码器执行语音处理算法时,可以调整多个迭代轮。 迭代可以对应于代数码本搜索。

    • A method and apparatus for modification of a speech signal indicative of a stream of speech data having a plurality of syllables. The method comprises the steps of mapping the stream of speech data from the speech signal into a stream of tone data according to a linguistic rule regarding the syllables for providing a tone signal indicative of the stream of tone data; forming a string of musical notes responsive to the tone signal for providing a carrier signal indicative of the string of musical notes; modulating the carrier signal with the speech signal for providing a modified signal; and providing an audible signal representative of the speech signal, musically modified according to the linguistic rule. The linguistic rule includes an assignment of a tone to a syllable of the speech data based on a vowel of the syllable, a consonant of the syllable, the intonation of the syllable for a monosyllabic language. The musically modified speech signal can be used to indicate an incoming telephone call, a message left on a telephone, a scheduled event, or the like.
    • 一种用于修改指示具有多个音节的语音数据流的语音信号的方法和装置。 该方法包括以下步骤:根据关于用于提供表示音频数据流的音调信号的音节的语言规则,将语音数据流从语音信号映射到音调数据流中; 响应于音调信号形成一串音符,以提供指示音符串的载波信号; 用语音信号调制载波信号以提供修改的信号; 并且根据语言规则提供代表语音信号的可听信号,该语音信号被音乐修改。 语言规则包括基于音节的元音,音节的辅音,单音节语言的音节的音调,将音调分配给语音数据的音节。 音乐修改的语音信号可以用于指示进入的电话呼叫,留在电话上的消息,预定的事件等。
