Title: M.E.S.S. Mobile E-mail Speech System


1
M.E.S.S. Mobile E-mail Speech System
  • E-mail for people on the move

2
Team Members
  • Jim Cheung
  • Dimitrios Fourlas
  • Kanaris Paraskevopoulos
  • Kristen Sparrowhawk
  • Ahsan Upal

3
Introduction
  • The Mobile E-mail Speech System is a voice
    controlled e-mail to speech system.
  • It retrieves e-mail from a server and relays it
    to the user through speech.

5
Requirements
  • System downloads e-mails remotely from a server
  • System is voice activated
  • Implemented in vehicles or for visually impaired
    persons

6
Requirements - contd.
  • Voice recognition is used for command input
  • Text to speech synthesizer is utilized to talk to
    the user, including reading e-mails and systems
    menus
  • Uses cellular technology to dial into the mail
    server

7
Hardware Components- Prototype
  • Server
  • Laptop Computer
  • Text to Speech Processor
  • F.M. Transmitter
  • Modem Connection
  • Condenser Microphone
  • FM Receiver

8
Text to Speech Processor
  • High speech quality, unlimited vocabulary
  • Converts any ASCII text into speech
  • Serial interface
  • Settings for pitch, volume, speed and voice can
    be changed without resetting the chipset

9
Mail Server Setup
  • LINUX operating system
  • Standard SMTP e-mail server
  • Configured for PPP dial-in access

10
Connection Method
  • Current Normal land phone connection
  • Future Digital Cellular Link

11
Software Components
  • User Interface
  • Voice Recognition
  • Connection/Download
  • Parsing/Updating e-mails
  • Software was designed in C/C, BASIC and PERL
    languages.

12
User Interface
  • Console Interface (text based)
  • Designed in C and C
  • User friendly with minimal inputs
  • Able to edit information
  • Able to accept voice and keypad inputs

13
User Interface - Hierarchy
14
Parsing E-mail
  • Filters raw e-mail message file to contain only
    the pertinent elements
  • Senders name
  • Date of e-mail
  • Subject of e-mail
  • Body of the e-mail message
  • Designed to search for these elements only. All
    other headers and attachments are discarded.

Voice Recognition
17
F.M. Transmitter
  • Power supply voltage DC 1.5 V
  • Current consumption 7.4 mA
  • Frequency coverage 91-97 MHz
  • Transmitter power 11.1 mW
  • Industry Canada compliant
  • Hardwired into vehicle stereo system

18
Testing
  • Modular testing
  • first individually, then bringing the modules in
    to work together as a whole
  • Primarily consisted of debugging source code
  • Connectivity to the e-mail server
  • Overall system functionality

19
Hardware Components -Future Implementation
  • Toronto MicroElectronics, Inc. - 2111 industrial
    single board computer (SBC)
  • Modem and cellular telephone
  • DoubleTalk RC8650 text to speech
  • CrystalFontz 20 X 4 serial LCD display
  • Numerical Keypad
  • F.M. Transmitter
  • Vehicle Stereo System

20
Future Considerations
  • To be actually implemented in a vehicle
  • Adding Internet Service Providers (ISPs)
  • Including code to handle HTML enriched mail (ie.
    Hotmail, Yahoo mail)
  • Better Noise Reduction and Voice Recognition
  • Implement Data Compression
  • Ability to send e-mails
  • Integration with other mobile systems such as GPS
    receivers, MP3 players and in dash cellular
    phones.
