  3. HLD / LLD of OCR 1 0..1 1.. 0..1 1.. 0..1

  4. HLD / LLD of OCR Feature Extraction • Assigning PixelNum to each class • Calculating LociNum using Characteristic • Loci approach • Creating Feature Vector for each segment Classification • Creating 38 classes • Creating Feature Vector for each class • Applying a Binary Mask • Calculating Euclidean Distance: • Classifying the input

  5. HLD / LLD for TTS

  6. Low level Design / TTS Word Pronunciation(UnitConcatenator) • Accepts the text • Checks the database for the word pronunciation • Reverts to “letter to sound rules” If the word doesn’t exist • outputs a sequence of phonemes • Passes the pronunciation to prosody stage Play Audio • Engine receives the phoneme • Loads the digital audio from a database • Does some pitch, time, and volume changes • Sends it out to the sound card.

  7. Overall Software Architecture OCR Package TTS Package • Main Method • Captures text image • Invokes OCR package • Sends extracted text to TTS package • Reads out the text

  8. Project Plan Term 3 • Implementing OCR and TTS engines in emulator environment • Integrating OCR and TTS engines Term 4 • Porting the complete package to the mobile platform • Testing the final package
