To extract text from pdf, you can refer to following codes which is based on a .NET pdf library:

PdfDocument document = new PdfDocument();
document.LoadFromFile(@"E:\sample.pdf");
StringBuilder content = new StringBuilder();
foreach (PdfPageBase page in document.Pages)
{
content.Append(page.ExtractText());
}
String fileName = "TextFromPDF.txt";
File.WriteAllText(fileName, content.ToString());

If your pdf file is less than 10 pages, you can use it's free version:

Dear Yogesh,
Text to speech requires text on output. PDF is not text. As soon as you extract text from some PDF document, you can feed it to text-to-speech.
So first step is reading pdf file in text

Than second step is use text-to-speech in .NET

Thanks,
Shakti

You can use Adobe PDF IFilter Library to convert a PDF document to text.
