How to convert wav file into Text format using asp.net mvc4

Hi,

i have a wave file and want to convert that into Text format using asp.net

i tried the below code but it not understood when audio file is end.

Index

@model MvcApplication1.Models.Home
@{
    ViewBag.Title = "Home Page";
}
We suggest the following:

@using (Html.BeginForm())
{
    <input type="button" onclick="callfun()" value="Get" />
    @Html.HiddenFor(m => m.txtval)
    @Html.LabelFor(m => m.txtval)
}
 
<script>
    function callfun() {
        $.ajax({
        url: 'Home/Find',
        dataType: "json",
        type: "GET",
        contentType: 'application/json; charset=utf-8',
                    //pageNo: 2, pageSize: 20 would not be posted to the action,
                    //it would be 3 and 5 as we specified it at ajax url
                    //and user would be null
        data: {},
        async: true,
        processData: false,
        cache: false,
        success: function (data) {
                    alert(data);
                },
        error: function (xhr) {
                    alert('error');
                }
        })
    }
</script>
