Reproductive Cloning01:27

Reproductive Cloning

32.5K
Reproductive cloning is the process of producing a genetically identical copy—a clone—of an entire organism. While clones can be produced by splitting an early embryo—similar to what happens naturally with identical twins—cloning of adult animals is usually done by a process called somatic cell nuclear transfer (SCNT).
Somatic Cell Nuclear Transfer
In SCNT, an egg cell is taken from an animal and its nucleus is removed, creating an enucleated egg. Then a somatic...

Cloning of Dolly the Sheep

7.0K
The first successfully cloned mammal was Dolly, a sheep, born on 5th July 1996 at Roslin Institute, Scotland. The cloned sheep was named after the American singer Dolly Parton. Dolly lived for seven years and died of respiratory complications, which is speculated to be due to the actual age of her DNA. Because the DNA in cloned cells belongs to an older individual,  the cloned individual’s life expectancy may be affected. Indeed, analysis of Dolly’s DNA revealed shorter...

科学领域:

  • 语音处理和人与计算机的交互.

背景情况:

  • 语音克隆合成语音模仿人类的声音特征.
  • 评估合成语音需要与人类语音进行比较,以获得可理解性和与人类相似性.

研究的目的:

  • 为了比较人类和语音克隆语音的可理解性,人类相似性和感知相似性.
  • 评估语音克隆在语音识别研究中的实用性.

主要方法:

  • 用正常听觉的年轻成年人进行了面具句子识别测试.
  • 来自五个人类说话者及其语音克隆的演讲以-6 dB SNR的噪音呈现.
  • 参与者评价了人类的相似性,并确定了声音的起源 (人类与克隆).

主要成果:

  • 人类语音和语音克隆语音的句子识别分数相似,尽管无意义的句子比有意义的句子更糟糕.
  • 在人类和克隆声音之间,人类相似度的评分是可比的.
  • 参与者准确地识别了不同的声音,但很难区分人类/克隆对,经常把克隆误认为是人类.

结论:

  • 语音克隆显示出作为评估语音识别的可靠工具的潜力,与人类语言相比.
  • 语音合成和自动语音识别对于研究人类语音感知非常有价值.
