Detailed Description
This is the SPHDEC1 speech decoder interface. Several of the data types in this API are specified by the XDM ISPHDEC1 interface; please see the XDM documentation for those details.
Macro Definition Documentation
Special value for timeout parameter indicating never timeout.
#define SPHDEC1_VISATYPE "ti.sdo.ce.speech1.ISPHDEC1" |
#define SPHDEC1_STUBSNAME "SPHDEC1_STUBS" |
Name of stub functions. Use this name when registering the SPHDEC1_STUBS functions with Engine_addStubFxns.

Typedef Documentation
Opaque handle to a SPHDEC1 codec.
Defines the creation time parameters for all ISPHDEC1 instance objects.
@remarks Some of the fields in this structure are optional and depend
on the class of speech decoder you're creating.
@remarks This structure may be extended by individual codec implementations allowing customization with vendor specific parameters. The presence of vendor specific extensions will be detected by the value of the @c size parameter.
Defines the input arguments for all ISPHDEC1 instance process function.
Defines the run time output arguments for all ISPHDEC1 instance objects.
@remarks This structure may be extended by individual codec implementations allowing customization with vendor specific parameters. The presence of vendor specific extensions will be detected by the value of the @c size parameter.
This structure defines the codec parameters that can be modified after creation via ISPHDEC1_Fxns.control().
@remarks It is not necessary that a given implementation support all
dynamic parameters to be configurable at run time. If a
particular algorithm does not support run-time updates to
a parameter that the application is attempting to change
at runtime, it may indicate this as an error.
@remarks This structure may be extended by individual codec implementations allowing customization with vendor specific parameters. The presence of vendor specific extensions will be detected by the value of the @c size parameter.
Defines instance status parameters.
@remarks This structure may be extended by individual codec implementations allowing customization with vendor specific parameters. The presence of vendor specific extensions will be detected by the value of the @c size parameter.
Function Documentation
Execute the control() method in this instance of a speech decoder algorithm.
- Parameters:
-
[in] | handle | Handle to a created speech decoder instance. |
[in] | id | Command id for XDM control operation. |
[in] | params | Runtime control parameters used for decoding. |
[out] | status | Status info upon completion of decode operation. |
- Precondition:
handle
is a valid (non-NULL) speech decoder handle and the speech decoder is in the created state.
- Return values:
-
- See also:
- SPHDEC1_create()
-
SPHDEC1_delete()
-
ISPHDEC1_Fxns.control()
Create an instance of a speech decoder algorithm.
Instance handles must not be concurrently accessed by multiple threads;
each thread must either obtain its own handle (via SPHDEC1_create()) or
explicitly serialize access to a shared handle.
@param[in] e Handle to an opened engine.
@param[in] name String identifier of the type of speech decoder
to create.
@param[in] params Creation parameters.
@retval NULL An error has occurred.
@retval non-NULL The handle to the newly created speech decoder
instance.
@remarks @c params is optional. If it's not supplied, codec-specific
default params will be used.
@remark Depending on the configuration of the engine opened, this
call may create a local or remote instance of the speech1
decoder.
@remarks In general, @c name is the name of the codec configured by the system integrator. However, an optional "argument string" may be appended to the codec name, to allow the codec's configured priority and/or the heaps where its memory will be allocated, to be overridden. This optional argument string is of the form <b>":priority"</b>, <b>":priority:flag"</b>, or <b>"::flag"</b>.
Delete the instance of a speech decoder algorithm.
- Parameters:
-
[in] | handle | Handle to a created speech decoder instance. |
- Precondition:
handle
is a valid (non-NULL) handle which is in the created state.
- Postcondition:

- See also:
- SPHDEC1_create()

- Parameters:

[out] | outBuf | A buffer descriptor containing the output buffer. |
[in] | inArgs | Input Arguments. |
[out] | outArgs | Output Arguments. |
- Precondition:
handle
is a valid (non-NULL) speech decoder handle and the speech decoder is in the created state.
