Selection of preferential pitch value for speech processing

21:

• A method of using a processing circuitry for selecting a preferential pitch lag value from a plurality of pitch lag values, including a first pitch lag value and a second pitch lag value, for coding an input speech signal, the method comprising:
• determining a first timing relationship between a previous pitch lag value and at least one of the plurality of pitch lag values;
• determining a second timing relationship between the first pitch lag value and the second pitch lag value;
• favoring one of the first pitch lag value and the second pitch lag value based on the first timing relationship and the second timing relationship to select one of the first pitch lag value and the second pitch lag value as the preferential pitch lag value;
• and
• converting the input speech signal into an encoded speech using the preferential pitch lag value.

27:

• A processing circuitry for selecting a preferential pitch lag value from a plurality of pitch lag values, including a first pitch lag value and a second pitch lag value, for coding an input speech signal, the processing circuitry comprising elements configured to:
• determine a first timing relationship between a previous pitch lag value and at least one of the plurality of pitch lag values;
• determine a second timing relationship between the first pitch lag value and the second pitch lag value;
• favor one of the first pitch lag value and the second pitch lag value based on the first timing relationship and the second timing relationship to select one of the first pitch lag value and the second pitch lag value as the preferential pitch lag value;
• and
• convert the input speech signal into an encoded speech using the preferential pitch lag value.

33:

• A computer medium containing an executable code for execution by processing circuitry for selecting a preferential pitch lag value from a plurality of pitch lag values, including a first pitch lag value and a second pitch lag value, for coding an input speech signal, the computer medium comprising:
• code for determining a first timing relationship between a previous pitch lag value and at least one of the plurality of pitch lag values;
• code for determining a second timing relationship between the first pitch lag value and the second pitch lag value;
• code for favoring one of the first pitch lag value and the second pitch lag value based on the first timing relationship and the second timing relationship to select one of the first pitch lag value and the second pitch lag value as the preferential pitch lag value;
• and
• code for converting the input speech signal into an encoded speech using the preferential pitch lag value.
