SqlDataReader times out when many records in SQL Server table

I have stored procedure Topounce that gets the top record from a dynamic table and speaks it out of the PC. When the there are too many records it times out in

SqlDataReader dr2 = select.ExecuteReader() 

Right now there are around 750 records. I already tried CommandTimeOut = 0 and it took around 10 min for the record to be spoken. Is there a way around this?

Here is the error:

Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding.

Code:

try
{
   using (SqlConnection connStr2 = new SqlConnection(ConfigurationManager.ConnectionStrings["ConnString"].ConnectionString))
   {
      //Selects top record from vwAnno
      SqlCommand select = new SqlCommand("Topounce", connStr2);
      select.CommandType = CommandType.StoredProcedure;                   
      select.Parameters.AddWithValue("@ID", (string)Num);

      connStr2.Open();

      SqlDataReader dr2 = select.ExecuteReader();   // TIMES OUT HERE

      //Reads record in vwAnnounce
      while (dr2.Read())
      {
          //do work
      }

      dr2.Close(); //Close Datareader connection
      connStr2.Close();
}

UPDATE here is the store procedure.

     USE [Queue]
      GO
      /****** Object:  StoredProcedure [dbo].[TopRowViewAnnounce]    Script Date:         06/01/2013 11:55:50 ******/
       SET ANSI_NULLS ON
     GO
     SET QUOTED_IDENTIFIER ON
     GO
     ALTER PROCEDURE [dbo].[TopRowViewAnnounce] 
    @QueueID int

    AS


    BEGIN

 SELECT TOP 1 id, qdate, ticket_number, QID, received, displaynum, station, transcodevoiced FROM vwAnnounce WHERE QID = @ID ORDER by received ASC
    END

The reason I did a store procedure its because I thought it was going to help the timeout. I originally had it like this.

SqlCommand select = new SqlCommand("SELECT TOP 1 id, qdate, ticket_number, QID, received, displaynum, station, transcodevoiced FROM vwAnnounce WHERE QID = @ID ORDER by received ASC", connStr2);
  select.CommandType = CommandType.StoredProcedure;                   
  select.Parameters.AddWithValue("@ID", (string)Num);

  connStr2.Open();

  SqlDataReader dr2 = select.ExecuteReader();   // TIMES OUT HERE

I still havent got the solution. Anybody?
