Today over 90% of letter mail is sorted by machines. However, 5-7% of the volume still has to be sorted manually, either because the address is difficult to read or because the physical format of the mail does not fit the sorting machines. Abakus Voice Sorting Solution based on voice technology is designed to sort out letters rejected by sorting stations with enhanced productivity and high sorting quality.
Fast sorting speedImproved sorting quality and speed of problematic mail compared to OCR sorting.
Lean unitDoesn’t require special sorting stations, utilizes existing or custom bin structures.
Easy to useNo special training nor prior sorting experience needed.
Only industrial PC with network connection and a headset is needed.
Intelligent and powerful
Can handle routing and sequencing needs, both online and offline.

than the large sorting machines. Sorting based on voice recognition is fast and error free.

eliminating work phases from the repetitive process.
|Sorting bin||Freely selectable, based on local needs.||Fixed||• Reliable OCR resolution requires high quality camera |
and stable lightning conditions. This is normally achieved
with an embedded OCR station and fixed lightning.
Since each letter goes from OCR reader directly to bin,
the bin need to be integrated to the OCR station. This might not support well local conditions such as route and sequencing differences.
• Voice sorting doesn’t require special sorting stations. It can utilize existing or custom bin structures.

• Voice sorting station is a lean unit. Only industrial PC with network connection and a headset is needed. Local conditions can easily be adapted.
