亚马逊转录

http://aws.amazon.com/transcribe/
亚马逊转录 makes it easy for developers to add speech-to-text capabilities to their applications. Audio data is virtually impossible for computers to search and analyze. Therefore, recorded speech needs to be converted to text before it can be used in applications. Historically, customers had to work with transcription providers that required them to sign expensive contracts and were hard to integrate into their technology stacks to accomplish this task. Many of these providers use outdated technology that does not adapt well to different scenarios, 比如联络中心常见的低保真电话音频, 这就导致了较差的准确性.

亚马逊转录使用深度学习过程, 称为自动语音识别(ASR), 将语音快速准确地转换为文本. 亚马逊转录可以用来转录客户服务电话, 自动化字幕, and generate metadata for media assets to create a fully searchable archive.

瑞士电信电视语音助手

http://www.swisscom.ch/en/residential/help/device/blue-tv/voice-assistant.html
Voice control allows you to operate the Swisscom TV-Box with your voice. 瑞士人通常能流利地说一种以上的语言, if needed, 即使在同一个句子中,也能轻松地在它们之间切换吗. This phenomenon is called code-switching in the field of speech recognition.

瑞士电信的电视语音助手也出现了同样的现象. 在这种情况下, the user might switch between languages when searching for a foreign actor; for example, "帮我找一部格姆拉德·德帕迪约的电影," where the intent is spoken in English and the entity is spoken in French.

After investigating different approaches for code-switching and multilingual speech recognition, I improved the system's word-error rate by 10% in code-switching scenarios.
