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.

Function Documentation

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. Definition at line 67 of file record.c. Referenced by record_sample_write().

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. Definition at line 97 of file record.c. Referenced by record_sample_close().

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. Definition at line 126 of file record.c. Referenced by record_sample_open().

void record_sample_open (   )

Open temporary file for starting recording. Definition at line 146 of file record.c. Referenced by main_recognition_loop(), and RealTimePipeLinePrepare().

void record_sample_write (  SP16 *  speech, int  samplenum )

Append speech segment to file previously opened by record_sample_open(). Parameters: speech  [in] speech buffer samplenum  [in] length of above in samples Definition at line 175 of file record.c. Referenced by adin_cut_callback_store_buffer(), and RealTimePipeLine().

void record_sample_close (   )

End recording. Close the current temporary recording file, and rename the temporary file to the final time-stamp file name. Definition at line 207 of file record.c. Referenced by main_recognition_loop().
