　　谷歌旗下DeepMind在語音生成領域取得突破

　　Google’s DeepMind division has claimed a big leap forward in producing computer-generatedspeech, potentially bringing forward the day when machines sound as natural as humans.

　　谷歌(Google)旗下的DeepMind稱，在計算機語音生成領域取得巨大飛躍。這一技術進步可能會令機器像人一樣自然發(fā)聲的一天提前到來。

　　Researchers at the UK-based artificial intelligence arm said tests of their system with humanlisteners, though unavoidably subjective, had shown that the technology halves the qualitygap that exists between today’s computer systems and human speech.

　　One person familiar with the research said the system, called WaveNet, was not being employedin any of Google’s products yet, and that the massive computing power it needed to generatespeech made it impractical for real world use for the foreseeable future.

　　一位知情人士表示，這一名叫WaveNet的系統(tǒng)尚未被用于谷歌任何產(chǎn)品。該技術在生成語音時需要極大的運算能力，令它在可以預期的未來無法實際運用到真實世界。

　　周四，WaveNet的相關研究以及一系列該系統(tǒng)生成的語音樣本被發(fā)布到網(wǎng)上。
