  7. Controllable speech output SVOX SpeechCreate Prosody modification • Take the first exit on your left. • Take the first exit on your left.

  8. SpeechCreate: Urgency • Designing the content of the message, e.g. from traffic-congestion forecast: • "slow down!" • Use SVOX SpeechCreate to specify: • level of urgency, emotion • Pitch, speed • Optimize prompts to suit the demands of the driving situation to ensure a better driver response time

  9. Problems with voice talents Lead Time • Lead time for additional recordings is typically in the order of weeks • Desired lead time shortly before production is in the order of hours or days Availability • Professional speakers are not always available • Speakers can become completely unavailable. In this case, all recordings have to be done from scratch Quality • The sound of a voice changes over time and from day to day – old and new recordings do not match well Cost

  11. Source: Sue Ellen Reager, “Preparing for Localzation”, Speech Technology Magazine, January/February 2008 “Preparing for Localization” • To achieve an acceptable level of localization, follow these basic steps: • Basic Translation • Nationalization • Regionalization • Expatriates • Customization for Corporations and Industries • Forms of Addresses • Male or Female

  12. Localization pitfalls (1/3) • English • “turn left, Sequoia Drive.” • “turn left onto Sequoia Drive.”

  13. Localization pitfalls (1/3) • English • “turn left, Sequoia Drive.” • “turn left onto Sequoia Drive.” • Spanish • gire a la derecha, Avenida de Andalucía • la Avenida de Andalucía • el Camino Real • el Carril Principal

  19. Mixed-Linguality Place and Street Names for Signpost Reading • Major place names often have an expected pronunciation depending on the language: • e.g. Paris(EN) Paris(FR) Paris(DE) • e.g. Brussels(EN) Bruxelles(FR) Brüssel(DE) • For other place names, SVOX TTS maps the pronunciation to the HMI language using the same voice: • e.g. a Dutch voice saying „Gravelines“ (French town) • e.g. A French voice saying „Borssele“ (Dutch town) SAMPA 20

  20. Mixed-linguality Flexible, interlingual approach to phoneme-mapping across languages: en-UK ru-RU de-DE es-MX ca-FR nl-NL sv-SE EXAMPLES (5MB SVOX Automotive)
