VoiceTra: Your Pocket Speech Translator for Seamless Travel

VoiceTra is a free, user-friendly speech translation app supporting 31 languages. Perfect for enhancing your travel experience or assisting visitors to Japan, VoiceTra translates spoken words into different languages using high-precision speech recognition, translation, and speech synthesis technologies developed by the National Institute of Information and Communications Technology (NICT).

Key Features:

  • Bi-directional Translation: Instantly switch translation direction for effortless communication between two people speaking different languages using a single device.
  • Text Input Support: Offers text input for languages lacking speech input capabilities.
  • Contextual Understanding: While usable as a dictionary, inputting sentences yields more accurate translations due to contextual interpretation.
  • Wide Range of Applications: Ideal for travel situations including transportation (bus, train, taxi, airport), shopping, hotels (check-in/out), and sightseeing. It has also been utilized as a disaster-prevention/relief app.

Supported Languages: Japanese, English, Chinese (Simplified & Traditional), Korean, Thai, French, Indonesian, Vietnamese, Spanish, Myanmar, Arabic, Italian, Ukrainian, Urdu, Dutch, Khmer, Sinhala, Danish, German, Turkish, Nepali, Hungarian, Hindi, Filipino, Polish, Portuguese, Brazilian Portuguese, Malay, Mongolian, Lao, and Russian.

Important Considerations:

  • Internet Connection Required: An internet connection is necessary for operation. Translation speed may vary depending on network connectivity.
  • Text Input Limitations: Text input availability depends on your device's OS keyboard support.
  • Font Compatibility: Proper font installation is crucial for accurate character display.
  • Server Dependency: Service interruptions may occur during server downtime.
  • Data Usage: Users are responsible for all data charges incurred. International roaming fees can be substantial.
  • Research Application: VoiceTra is a research application. Data collected is used to improve speech translation technologies. While business use is permitted, consider licensed services for continuous, professional use. See our Terms of Use for details: https://voicetra.nict.go.jp/en/attention.html

Pas mal pour un traducteur gratuit ! La reconnaissance vocale est plutôt précise, mais parfois il faut répéter. J'aime bien l'interface simple. 👍
