Detailed Description

Record speech inputs into successive files.

These functions record each input data to the corresponding file with file name of their time stamp in a format of "YYYY.MMDD.HHMMSS.wav". The audio format is Microsoft WAVE, 16bit, PCM (no compression).

The recording will not be stored in memory, instead it will be directly recorded to a temporary file on the fly. After an end-of-sentence found and the first pass ends, the temporary file will be moved to the final filename descrived above.

static void timestring	(	char *	t,
		int	maxlen
	)			[static]

Make base filename string from current system time.

Parameters:

	t	[out] string buffer to hold the result string.
	maxlen	[in] the length of t.

static void make_record_filename	(	char *	buf,
		int	buflen,
		char *	filename
	)			[static]

Make actual file path name from base file name. The recording directory should be specified by the global variable "record_dirname".

Parameters:

	buf	[out] buffer to hold the result string of this function
	buflen	[in] maximum length of buf.
	filename	[in] base filename.

static void make_tmp_filename	(	char *	buf,
		int	buflen
	)			[static]

Make temporary filename to store the incoming data while recording.

Parameters:

	buf	[out] pointer of buffer to hold the resulting file name.
	buflen	[in] maximum length of buf.

Parameters:

	speech	[in] speech buffer
	samplenum	[in] length of above in samples
