c++ - Windows 上的 Flite API 错误

Question

我为windows构建flite，代码是:

#include "..\\include\\flite.h"
cst_voice *register_cmu_us_kal();
int main(int argc, char **argv)
{    cst_voice *v;
    if (argc != 2)
    {
        fprintf(stderr, "usage: flite_test FILE\n");
        exit(-1);
    }
    flite_init();
    v = new_voice();
    flite_text_to_speech("This is a test",v,"play");
    return 0;
}

但我收到 printf 消息“usage:”，如果我删除它，我会收到“尝试访问 -1 类型 val flite 中的词典”。我在 Windows 上，所以我在没有文档中的参数的情况下调用 project.exe。 你知道如何解决这个问题吗？

如评论中所述，您应该删除参数计数 (argc) 检查。

此外:当您调用 new_voice 方法时，您会得到未初始化的 cst_voice 并且您仍然无法使用它。

这就是你得到错误的原因:

tried to access lexicon in -1 type val flite

这意味着 lex (cst_lexicon) 在 cst_voice 结构中仍未初始化。

我想您需要执行类似以下代码的操作:

cst_voice *register_cmu_us_no_wave()
{
    cst_voice *v = new_voice();
    cst_lexicon *lex;

    v->name = "no_wave_voice";

    /* Set up basic values for synthesizing with this voice */
    usenglish_init(v);
    feat_set_string(v->features,"name","cmu_us_no_wave");

    /* Lexicon */
    lex = cmu_lex_init();
    feat_set(v->features,"lexicon",lexicon_val(lex));

    /* Intonation */
    feat_set_float(v->features,"int_f0_target_mean",95.0);
    feat_set_float(v->features,"int_f0_target_stddev",11.0);

    feat_set_float(v->features,"duration_stretch",1.1); 

    /* Post lexical rules */
    feat_set(v->features,"postlex_func",uttfunc_val(lex->postlex));

    /* Waveform synthesis: diphone_synth */
    feat_set(v->features,"wave_synth_func",uttfunc_val(&no_wave_synth));

    return v;
}
