Abstract
Apparatus and method to allow retrieval of voice messages deleted from the voice message memory of a voice messaging system. A voice messaging system such as a telephone answering device includes a deleted voice message memory for storing voice messages deleted from the voice message memory. The deleted voice messages stored in the deleted voice message memory are retrievable by the user for review subject to rules for permanent deletion of the deleted voice messages (e.g., after a period of time, when the deleted voice message memory approaches capacity, periodically, etc.).
Claims25
A voice messaging system, comprising:
- a controller:
- a user accessible voice message memory to store at least one user accessible voice message;
- and
- a deleted voice message memory to store at least one user deleted voice message;
- wherein a voice message is initially compressed and stored in said user accessible voice message memory, and upon activation of a user selectable keypad option to delete said user accessible voice message from said user accessible voice message memory, said voice message is automatically re-compressed, moved and stored in said deleted voice message memory, such that, after re-compression, said voice message is more highly compressed than when it was stored in said user accessible voice message memory.
A method for managing a user deleted compressed voice message from a voice messaging system, comprising:
- automatically removing said user deleted compressed voice message stored in a user accessible first memory area upon activation of a user selectable keypad option to delete said user deleted compressed voice message from said user accessible first memory area;
- re-compressing said user deleted compressed voice message to produce a re-compressed voice message after said user selectable keypad option is activated, such that, after re-compression, said re-compressed voice message is more highly compressed than the user deleted compressed voice message initially stored in said user accessible voice message memory;
- and
- storing said re-compressed voice message in a second memory area.
Apparatus for retrieving a user deleted compressed voice message from a voice messaging system, comprising:
- means for automatically removing said user deleted compressed voice message stored in a user accessible first memory area upon activation of a user selectable keypad option to delete said user deleted compressed voice message from said user accessible first memory area;
- means for re-compressing said user deleted compressed voice message to produce a re-compressed voice message;
- means for storing said re-compressed voice message in a deleted voice message memory;
- and
- means for retrieving said re-compressed voice message from said deleted voice message memory for playback.
A voice messaging system, comprising:
- a controller;
- a user accessible voice message memory to store at least one user accessible voice message;
- and
- a deleted voice message memory to store at least one user deleted voice message;
- wherein a voice message is initially compressed and stored in said user accessible voice message memory, and upon activation of a user selectable keypad option to delete said voice message from said user accessible voice message memory, said voice message is re-compressed, moved and stored in said deleted voice message memory, such that, after re-compression, said voice message is more highly compressed than when it was stored in said user accessible voice message memory;
- and
- wherein a total storage space allocated to each of said user accessible voice message memory and said deleted voice message memory from a common total memory space is dynamically adjusted to optimize a space available for said user accessible voice message memory and said deleted voice message memory.
Apparatus for retrieving a user deleted compressed voice message from a voice messaging system, comprising:
- means for removing said user deleted compressed voice message stored in a user accessible first memory area upon activation of a user selectable keypad option to delete said compressed voice message from said user accessible first memory area;
- means for re-compressing said user deleted compressed voice message to produce a re-compressed voice message;
- means for storing said re-compressed voice message in a second memory area;
- means for retrieving said re-compressed voice message from said second memory area for playback;
- and
- means for dynamically adjusting the total storage space allocated to each of said user accessible first memory area and said second memory area from a common total memory space to optimize a space available for said user accessible first memory area and said second memory area.
