Comparison with Other SDKs
Remember that SpeechKit is just one of many frameworks you can use for speech detection and vocalization. There are a number of other frameworks you may want to consider:
- OpenEars: It’s FREE but only has support for English and Spanish.
-
CeedVocal: It’s available in 6 languages (English, French, Dutch, German, Spanish and Italian). It’s not free, but you can buy licences per application or pay a one-time fee of 6000 Euros for an unlimited number of applications. Each license is good for one language, but you can add additional languages as needed. Try working with the trial version first.
-
iSpeech: This SDK has support for 20 languages as of now, and is free for mobile apps.
Both OpenEars and CEEDVocal share the issue of low function in a noisy environment. Out of all these frameworks Nuance’s SpeechKit supports more languages, understands different accents and remains useful when there is a lot of background noise.
However, there are two scenarios where you may need to consider other frameworks. If your application needs to process speech recognition in offline mode, then you might like OpenEars. All other frameworks require network connectivity.
SpeechKit requires that port 51001 be left open. Some non-Windows firewalls, and various antivirus software may disable port 51001. This will cause a connection error while using SpeechKit. If that occurs, you need to configure the software to open the port.
