Now just a quick talk about some best practices. We’re making speech recognition available for free to all apps but we do have some reasonable limits in place so that the service remains available to everyone. Individual devices may be limited in the amount of recognitions that can be performed per day.

Apps may also be throttled globally on a request per day basis. Like other service backed APIs,for example CLGO Coder,be prepared to handle network and rate limiting failures. If you find that you’re routinely hitting your throttling limits,please let us know.

It’s also important to be aware that speech recognition can have a high cost in terms of battery drain and network traffic.

For iOS 10 we’re starting with a strict audio duration limit of about one minute which is similar to that of keyboard dictation.

请注意“让我们知道”部分 – Apple显然希望开发人员使用这个新API,因此如果您发现它不能满足您的需求,他们可能会提供帮助.
