This paper discusses the advantages and challenges of using multimodal and voice technologies for field data collection. Current developments in the multimodal, mobile, field data communications are discussed. VoiceXML technology for speech-enabled information retrieval and input using natural speech over the phone is described. Two field prototype applications developed using this technology are also discussed, including speech-based inventory and time management services for field users. The author presents the results of performance studies for the prototypes and discusses the pilot usability study conducted on a group of potential users.
