抱歉,我不太确定您指的是什么类型的语音识别界面。不过,下面是一个简单的基于C语言的控制台程序,可以通过录制音频并将其转换为文本:
```c
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <sphinxbase/ad.h>
#include <pocketsphinx.h>
#define MODELDIR "/usr/local/share/pocketsphinx/model"
int main(int argc, char *argv[])
{
ps_decoder_t *ps;
cmd_ln_t *config;
FILE *fh;
char const *hyp, *uttid;
int16 buf[512];
int32 score;
size_t nsamp;
config = cmd_ln_init(NULL, ps_args(), TRUE,
"-hmm", MODELDIR "/en-us/en-us",
"-lm", MODELDIR "/en-us/en-us.lm.bin",
"-dict", MODELDIR "/en-us/cmudict-en-us.dict",
NULL);
ps = ps_init(config);
ad_rec_t *ad = ad_open_dev("default", (int)cmd_ln_float32_r(config, "-samprate"));
if (ad_start_rec(ad) < 0) {
fprintf(stderr, "Failed to start recording\n");
return 1;
}
ps_start_utt(ps);
while (1) {
nsamp = ad_read(ad, buf, 512);
ps_process_raw(ps, buf, nsamp, FALSE, FALSE);
if (nsamp < 0) {
fprintf(stderr, "Failed to read audio\n");
return 1;
}
if (ps_get_in_speech(ps)) {
printf("Listening...\n");
fflush(stdout);
}
else {
printf("Processing...\n");
fflush(stdout);
}
hyp = ps_get_hyp(ps, &score);
if (hyp != NULL) {
printf("%s\n", hyp);
fflush(stdout);
ps_end_utt(ps);
ps_start_utt(ps);
}
}
ad_close(ad);
ps_free(ps);
cmd_ln_free_r(config);
return 0;
}
```
这个程序使用了CMU Sphinx声学模型和语言模型来进行语音识别。您需要安装Sphinxbase和Pocketsphinx来运行它。此外,您还需要一个音频输入设备(例如麦克风)来录制音频。
