Points of Caution

  • Prior to using Jspeak, you must read and accept both the terms and conditions and the privacy policy.
  • Data charges will be incurred to download, update, or use the Jspeak app (except when used on Wi-Fi).
  • For Jspeak to send the customer's spoken words as data to a server, or receive translation output, the customer must have a valid contract for data service with his or her mobile phone carrier. Data charges will vary according to usage of the service, but a flat rate data plan is strongly recommended.
  • Using Jspeak on international roaming will incur international roaming charges. (For details on international roaming charges, please check with your mobile phone carrier.)
  • This app may not operate properly or be usable with some phone models, OS versions, or mobile phone carriers.
  • Some regional pronunciations or dialects may not be recognized, even for supported languages.
  • The Jspeak service involves the use of translation technology, voice recognition technology, and language processing technology. Please be aware that NTT Docomo NTT DOCOMO is unable to guarantee the accuracy of these technologies. Voice recognition accuracy is affected by the distance from the smartphone when speaking and also by the volume of the spoken voice. To improve recognition accuracy, speak clearly in as quiet an environment as possible.
  • When a new version of the Jspeak app becomes available, some or all of the functioning of Jspeak may stop working until the app is updated.
  • The time required for the translation to appear may vary according to the amount of data traffic on the network or server.
  • Jspeak may not be available at times due to system maintenance. Also, service content, features, provisions, and term of use are subject to change without prior notice.
