例句与用法

Subjective testing indicates that the quality of cs - acelp is equivalent to that of the 32kbit / s adaptive differential pulse code modulation ( adpcm ) under error - free conditions and it outperforms g . 726 under error condition . in this paper , standard c is adopted in realization of the algorithm , presents program strategies and steps of algorithm of each module . the coder and decoder is tested by utterances with noise
用标准c语言仿真实现了该算法，计算了mos分值，女声： 4 . 180497 ，男声： 4 . 199782 ，并在相同的测试语句中加入噪声进行测试，含噪语句通过该编解码器，输出的合成语音用主、客观评价标准评价，与原始不含噪语音效果差别不大，平均mos分值为：女声4 . 1375 ，男声4 . 1668 ，说明该算法是优秀的编解码算法。
2g : in 1989 , two technologies from the " world of sound studio " are combined on a pc expansion card for the first time : fm synthesis made famous by yamaha synthesizers and 8 - bit pcm pulse code modulation at 11 . 25 khz . for a long time , " soundblaster " becomes synonymous with the term sound card , and the first step toward the pc as " multimedia machine " was taken
11989年，两项由world of sound studio发展出来的新科技首次被结合在个人电脑的扩充卡上：因为yamaha音源合成器以及8 - bit pcm pulse code modulation at 11 . 25 khz的兴起，使得fm音源成为这时期的主流，使用fm音源的声卡声霸卡soundblaster几乎成了该产品的代名词。
We made an improvement in overcoming the defects in speech signal adaptive delta modulation ( abbr . adm ) , such as slope overloading and grain noise . in this method , numerical sliding average filtering was used for filtering decoding speech signal . experiments and analyses indicate that the method makes waveforms in good agreement between the decoding of adm and the original pulse coding modulation ( abbr . pcm ) signal , and considerably improves , the playback speech quality in naturalness , legibility and under standability
针对语音信号自适应增量调制( adm )方式中斜率过载和颗粒噪声缺点，提出了一种改进方法，它利用滑动平均方法对解码后的信号进行数字滤波.试验和分析表明，该方法使解码后的信号波形与原脉冲编码调制( pcm )波形具有很好的一致性，使再生语音质量在自然度、清晰度和可懂度方面比改进前均有较大提高
